-<P>
-Functions are conveniently packaged reusable software: it would be a
-shame to have to duplicate a complex condition expression or logging
-directive in every placed it's used.  So, systemtap lets you define
-functions of your own.  Like global variables, systemtap functions may
-be defined anywhere in the script.  They may take any number of string
-or numeric arguments (by value), and may return a single string or
-number.  The parameter types are inferred as for ordinary variables,
-and must be consistent throughout the program.  Local and global
-script variables are available, but target variables are <EM>not</EM>.
-That's because there is no specific debugging-level context associated
-with a function.
-
-<P>
-A function is defined with the keyword <code>function</code> followed by a
-name.  Then comes a comma-separated formal argument list (just a list
-of variable names).  The <code>{ }</code>-enclosed body consists of any list
-of statements, including expressions that call functions.  Recursion
-is possible, up to a nesting depth limit.  Figure&nbsp;<A HREF="#fig:functions">6</A>
-displays function syntax.

-<P>
-Often, probes will want to share data that cannot be represented as a
-simple scalar value.  Much data is naturally tabular in nature,
-indexed by some tuple of thread numbers, processor ids, names, time,
-and so on.  Systemtap offers associative arrays for this purpose.
-These arrays are implemented as hash tables with a maximum size that
-is fixed at startup.  Because they are too large to be created
-dynamically for inidividual probes handler runs, they must be declared
-as global.  
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>global a</code></TD>
-<TD ALIGN="LEFT">declare global scalar or array variable</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>global b[400]</code></TD>
-<TD ALIGN="LEFT">declare array, reserving space for up to 400 tuples</TD>
-</TR>
-</TABLE>
-
-<P>
-The basic operations for arrays are setting and looking up elements.
-These are expressed in <code>awk</code> syntax: the array name followed by
-an opening <code>[</code> bracket, a comma-separated list of index
-expressions, and a closing <code>]</code> bracket.  Each index expression
-may be string or numeric, as long as it is consistently typed
-throughout the script.
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>foo [4,"hello"] ++ </code></TD>
-<TD ALIGN="LEFT">increment the named array slot</TD>

-<TD ALIGN="LEFT">compute a timestamp delta</TD>
-</TR>
-</TABLE>
-
-<P>
-Array elements that have not been set <EM>may</EM> be fetched, and return
-a dummy null value (zero or an empty string) as appropriate.  However,
-assigning a null value does not delete the element: an explicit
-<code>delete</code> statement is required.    Systemtap provides syntactic sugar
-for these operations, in the form of explicit membership testing and
-deletion.
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>if ([4,"hello"] in foo) { }</code></TD>
-<TD ALIGN="LEFT">membership test</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>delete times[tid()]</code></TD>
-<TD ALIGN="LEFT">deletion of a single element</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>delete times</code></TD>
-<TD ALIGN="LEFT">deletion of all elements</TD>
-</TR>
-</TABLE>
-
-<P>
-One final and important operation is iteration over arrays.  This uses
-the keyword <code>foreach</code>.  Like <code>awk</code>, this creates a loop that
-<EM>iterates over key tuples</EM> of an array, not just <EM>values</EM>.  In
-addition, the iteration may be <EM>sorted</EM> by any single key or the
-value by adding an extra <code>+</code> or <code>-</code> code.
-
-<P>
-The <code>break</code> and <code>continue</code> statements work inside
-<code>foreach</code> loops, too.  Since arrays can be large but probe
-handlers must not run for long, it is a good idea to exit iteration
-early if possible.  The <code>limit</code> option in the <code>foreach</code>
-expression is one way.  For simplicity, systemtap forbids any <EM>modification</EM> of an array while it is being iterated using a
-<code>foreach</code>.
-
-<P>

-a little.  There is a third type: statistics aggregates, or aggregates
-for short.  Instances of this type are used to collect statistics on
-numerical values, where it is important to accumulate new data quickly
-(<EM>without</EM> exclusive locks) and in large volume (storing only
-aggregated stream statistics).  This type only makes sense for global
-variables, and may be stored individually or as elements of an array.
-
-<P>
-To add a value to a statistics aggregate, systemtap uses the special
-operator <code>&lt;&lt;&lt;</code>.  Think of it like C++'s <code>&lt;&lt;</code> output
-streamer: the left hand side object accumulates the data sample given
-on the right hand side.  This operation is efficient (taking a shared
-lock) because the aggregate values are kept separately on each
-processor, and are only aggregated across processors on request.

-writes[execname()] &lt;&lt;&lt; count
-</PRE>
-
-<P>
-To read the aggregate value, special functions are available to
-extract a selected statistical function. <EM>The aggregate value
-cannot be read by simply naming it as if it were an ordinary
-variable.</EM>  These operations take an exclusive lock on the respective
-globals, and should therefore be relatively rare.  The simple ones
-are: <code>@min</code>, <code>@max</code>, <code>@count</code>, <code>@avg</code>, and
-<code>@sum</code>, and evaluate to a single number.  In addition, histograms
-of the data stream may be extracted using the <code>@hist_log</code> and
-<code>@hist_linear</code>.  These evaluate to a special sort of array that
-may at present<A NAME="tex2html8"

-Safety
-</H2>
-
-<P>
-The full expressivity of the scripting language raises good questions
-of safety.  Here is a set of Q&amp;A:
-
-<P>
-<DL>
-<DT></DT>
-<DD><B>What about infinite loops?  recursion?</B> A probe handler is
-bounded in time.  The C code generated by systemtap includes explicit
-checks that limit the total number of statements executed to a small
-number.  A similar limit is imposed on the nesting depth of function
-calls.  When either limit is exceeded, that probe handler cleanly
-aborts and signals an error.  The systemtap session is normally
-configured to abort as a whole at that time.
-
-<P>
-</DD>
-<DT></DT>
-<DD><B>What about running out of memory?</B>  No dynamic memory
-allocation whatsoever takes place during the execution of probe
-handlers.  Arrays, function contexts, and buffers are allocated during
-initialization.  These resources may run out during a session, and
-generally result in errors.
-
-<P>
-</DD>
-<DT></DT>
-<DD><B>What about locking?</B>  If multiple probes seek conflicting
-locks on the same global variables, one or more of them will time out,
-and be aborted.  Such events are tallied as ``skipped'' probes, and a
-count is displayed at session end.  A configurable number of skipped
-probes can trigger an abort of the session.
-
-<P>
-</DD>
-<DT></DT>
-<DD><B>What about null pointers? division by zero?</B>  The C code
-generated by systemtap translates potentially dangerous operations to
-routines that check their arguments at run time.  These signal errors
-if they are invalid.  Many arithmetic and string operations silently
-overflow if the results exceed representation limits.
-
-<P>
-</DD>
-<DT></DT>
-<DD><B>What about bugs in the translator?  compiler?</B>  While bugs
-in the translator, or the runtime layer certainly exist<A NAME="tex2html9"
-  HREF="footnode.html#foot353"><SUP>3</SUP></A>, our test suite gives some
-assurance.  Plus, the entire generated C code may be inspected (try
-the <code>-p3</code> option).  Compiler bugs are unlikely to be of any
-greater concern for systemtap than for the kernel as a whole.  In
-other words, if it was reliable enough to build the kernel, it will
-build the systemtap modules properly too.
-
-<P>
-</DD>
-<DT></DT>
-<DD><B>Is that the whole truth?</B>  In practice, there are several
-weak points in systemtap and the underlying kprobes system at the time
-of writing.  Putting probes indiscriminately into unusually sensitive
-parts of the kernel (low level context switching, interrupt
-dispatching) has reportedly caused crashes in the past.  We are
-fixing these bugs as they are found, and
-constructing a probe point ``blacklist'', but it is not complete.

-Systemtap attempts to resolve references to global symbols (probes,
-functions, variables) that are not defined within the script by a
-systematic search through the tapset library for scripts that define
-those symbols.  Tapset scripts are installed under the default
-directory named <code>/usr/share/systemtap/tapset</code>.  A user may give
-additional directories with the <code>-I DIR</code> option.  Systemtap
-searches these directories for script (<code>.stp</code>) files.
-
-<P>
-The search process includes subdirectories that are specialized for a
-particular kernel version and/or architecture, and ones that name only
-larger kernel families.  Naturally, the search is ordered from
-specific to general, as shown in Figure&nbsp;<A HREF="#fig:tapset-search">7</A>.

-
-<P>
-When a script file is found that <EM>defines</EM> one of the undefined
-symbols, that <EM>entire file</EM> is added to the probing session being
-analyzed.  This search is repeated until no more references can become
-satisfied.  Systemtap signals an error if any are still unresolved.
-
-<P>
-This mechanism enables several programming idioms.  First, it allows
-some global symbols to be defined only for applicable kernel
-version/architecture pairs, and cause an error if their use is
-attempted on an inapplicable host.  Similarly, the same symbol can be
-defined differently depending on kernels, in much the same way that
-different kernel <code>include/asm/ARCH/</code> files contain macros that
-provide a porting layer.
-
-<P>
-Another use is to separate the default parameters of a tapset routine
-from its implementation.  For example, consider a tapset that defines
-code for relating elapsed time intervals to process scheduling
-activities.  The data collection code can be generic with respect to
-which time unit (jiffies, wall-clock seconds, cycle counts) it can
-use.  It should have a default, but should not require additional
-run-time checks to let a user choose another.
-Figure&nbsp;<A HREF="#fig:tapset-default">8</A> shows a way.

-Probe point aliases</A>
-</H2>
-
-<P>
-Probe point aliases allow creation of
-new probe points from existing ones.  This is useful if the new probe
-points are named to provide a higher level of abstraction.  For
-example, the system-calls tapset defines probe point aliases of the
-form <code>syscall.open</code> etc., in terms of lower level ones like
-<code>kernel.function("sys_open")</code>.  Even if some future kernel
-renames <code>sys_open</code>, the aliased name can remain valid.
-
-<P>
-A probe point alias definition looks like a normal probe.  Both start
-with the keyword <code>probe</code> and have a probe handler statement block
-at the end.  But where a normal probe just lists its probe points, an
-alias creates a new name using the assignment (<code>=</code>) operator.
-Another probe that names the new probe point will create an actual
-probe, with the handler of the alias <EM>prepended</EM>.
-
-<P>
-This prepending behavior serves several purposes.  It allows the alias
-definition to ``preprocess'' the context of the probe before passing
-control to the user-specified handler.  This has several possible uses:
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>if ($flag1 != $flag2) next</code></TD>

-<P>
-Figure&nbsp;<A HREF="#fig:probe-alias">9</A> demonstrates a probe point alias
-definition as well as its use.  It demonstrates how a single probe
-point alias can expand to multiple probe points, even to other
-aliases.  It also includes probe point wildcarding.  These functions
-are designed to compose sensibly.

-Embedded C
-</H2>
-
-<P>
-Sometimes, a tapset needs provide data values from the kernel that
-cannot be extracted using ordinary target variables (<code>$var</code>).  This may be because the values are in complicated data structures, may
-require lock awareness, or are defined by layers of macros.  Systemtap
-provides an ``escape hatch'' to go beyond what the language can safely
-offer.  In certain contexts, you may embed plain raw C in tapsets,
-exchanging power for the safety guarantees listed in
-section&nbsp;<A HREF="node13.html#sec:safety">3.6</A>.  End-user scripts <EM>may not</EM> include
-embedded C code, unless systemtap is run with the <code>-g</code> (``guru''
-mode) option.  Tapset scripts get guru mode privileges automatically.
-
-<P>
-Embedded C can be the body of a script function.  Instead enclosing
-the function body statements in <code>{</code> and <code>}</code>, use <code>%{</code>
-and <code>%}</code>.  Any enclosed C code is literally transcribed into the
-kernel module: it is up to you to make it safe and correct.  In order
-to take parameters and return a value, a pointer macro <code>THIS</code> is
-available.  Function parameters and a place for the return value are
-available as fields of that pointer.  The familiar data-gathering
-functions <code>pid()</code>, <code>execname()</code>, and their neighbours are
-all embedded C functions.  Figure&nbsp;<A HREF="#fig:embedded-C">10</A> contains
-another example.
-
-<P>
-Since systemtap cannot examine the C code to infer these types, an
-optional<A NAME="tex2html13"
-  HREF="footnode.html#foot612"><SUP>4</SUP></A> annotation
-syntax is available to assist the type inference process.  Simply
-suffix parameter names and/or the function name with <code>:string</code> or
-<code>:long</code> to designate the string or numeric type.  In addition,
-the script may include a <code>%{</code> <code>%}</code> block at the outermost
-level of the script, in order to transcribe declarative code like
-<code>#include &lt;linux/foo.h&gt;</code>.  These enable the embedded C functions
-to refer to general kernel types.
-
-<P>
-There are a number of safety-related constraints that should be
-observed by developers of embedded C code.
-
-<OL>
-<LI>Do not dereference pointers that are not known or testable valid.
-</LI>
-<LI>Do not call any kernel routine that may cause a sleep or fault.
-</LI>
-<LI>Consider possible undesirable recursion, where your embedded C
-function calls a routine that may be the subject of a probe.  If that
-probe handler calls your embedded C function, you may suffer infinite
-regress.  Similar problems may arise with respect to non-reentrant
-locks.
-</LI>
-<LI>If locking of a data structure is necessary, use a
-<code>trylock</code> type call to attempt to take the lock.  If that fails,
-give up, do not block.

-Introduction</A>
-</H1>
-
-<P>
-Systemtap is a tool that allows developers and administrators to write
-and reuse simple scripts to deeply examine the activities of a live
-Linux system.  Data may be extracted, filtered, and summarized quickly
-and safely, to enable diagnoses of complex performance or functional
-problems.
-
-<P>
-
-<P>
-The essential idea behind a systemtap script is to name <EM>events</EM>,
-and to give them <EM>handlers</EM>.  Whenever a specified event occurs,
-the Linux kernel runs the handler as if it were a quick subroutine,
-then resumes.  There are several kind of events, such as entering or
-exiting a function, a timer expiring, or the entire systemtap session
-starting or stopping.  A handler is a series of script language
-statements that specify the work to be done whenever the event occurs.
-This work normally includes extracting data from the event context,
-storing them into internal variables, or printing results.
-
-<P>
-
-<P>
-Systemtap works by translating the script to C, running the system C
-compiler to create a kernel module from that.  When the module is
-loaded, it activates all the probed events by hooking into the kernel.
-Then, as events occur on any processor, the compiled handlers run.
-Eventually, the session stops, the hooks are disconnected, and the
-module removed.  This entire process is driven from a single
-command-line program, <code>stap</code>.

-
-<P>
-For further information about systemtap, several sources are available.
-
-<P>
-There are <code>man</code> pages:
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>stap</code></TD>
-<TD ALIGN="LEFT">systemtap program usage, language summary</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>stapfuncs</code></TD>
-<TD ALIGN="LEFT">functions provided by tapsets</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>stapprobes</code></TD>
-<TD ALIGN="LEFT">probes / probe aliases provided by tapsets</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>stapex</code></TD>
-<TD ALIGN="LEFT">some example scripts</TD>
-</TR>
-</TABLE>
-
-<P>
-Then, there is the source code itself.  Since systemtap is <EM>free
-software</EM>, you should have available the entire source code.  The
-source files in the <code>tapset/</code> directory are also packaged along
-with the systemtap binary.  Since systemtap reads these files rather
-than their documentation, they are the most reliable way to see what's
-inside all the tapsets.  Use the <code>-v</code> (verbose) command line
-option, several times if you like, to show inner workings.
-
-<P>
-Finally, there is the project web site
-(<code>http://sources.redhat.com/systemtap/</code>) with several articles,
-an archived public mailing list for users and developers
-(<code>systemtap@sources.redhat.com</code>), and a live CVS source
-repository.  Come join us!

-such as a script function.  This variable may have been elided by an
-optimizing compiler, or may not have a suitable type, or there might
-just be an annoying bug somewhere.  Try again with a slightly
-different probe point (use <code>statement()</code> instead of
-<code>function()</code>) to search for a more cooperative neighbour in the

-The simplest kind of probe is simply to <EM>trace</EM> an event.
-
-This is the effect of inserting strategically located <code>print</code>
-statements into a program.  This is often the first step of problem
-solving: explore by seeing a history of what has happened.
-
-<P>
-This style of instrumentation is the simplest.  It just asks systemtap
-to print something at each event.  To express this in the script
-language, you need to say where to probe and what to print there.

-Systemtap supports a number of built-in events.  The library of
-scripts that comes with systemtap, each called a ``tapset'', may
-define additional ones defined in terms of the built-in family.  See
-the <code>stapprobes</code> man page for details.    All these events are named using a unified syntax that
-looks like dot-separated parameterized identifiers:
-
-<P>
-<TABLE CELLPADDING=3>

-<TD ALIGN="LEFT">The startup of the systemtap session.</TD>

-<code>sys_open</code> in the kernel.</TD>

-<P>
-Let's say that you would like to trace all function entries and exits
-in a source file, say <code>net/socket.c</code> in the kernel.  The
-<code>kernel.function</code> probe point lets you express that easily, since
-systemtap examines the kernel's debugging information to relate object
-code to source code.  It works like a debugger: if you can name or
-place it, you can probe it.  Use
-<code>kernel.function("*@net/socket.c")</code> for the function entries, and
-<code>kernel.function("*@net/socket.c").return</code> for the exits.  Note
-the use of wildcards in the function name part, and the subsequent
-<code>@FILENAME</code> part.  You can also put wildcards into the file name,
-and even add a colon (<code>:</code>) and a line number, if you want to
-restrict the search that precisely.  Since systemtap will put a
-separate probe in every place that matches a probe point, a few
-wildcards can expand to hundreds or thousands of probes, so be careful
-what you ask for.
-
-<P>
-Once you identify the probe points, the skeleton of the systemtap
-script appears.  The <code>probe</code> keyword introduces a probe point, or
-a comma-separated list of them.  The following <code>{</code> and <code>}</code>
-braces enclose the handler for all listed probe points.
-<PRE>
-probe kernel.function("*@net/socket.c") { }
-probe kernel.function("*@net/socket.c").return { }
-</PRE>
-You can run this script as is, though with empty handlers there will
-be no output.  Put the two lines into a new file.  Run
-<code>stap -v FILE</code>.  Terminate it any time with <code>^C</code>.  (The
-<code>-v</code> option tells systemtap to print more verbose messages during
-its processing.  Try the <code>-h</code> option to see more options.)

-What to print</A>
-</H2>
-
-<P>
-Since you are interested in each function that was entered and exited,
-a line should be printed for each, containing the function name.  In
-order to make that list easy to read, systemtap should indent the
-lines so that functions called by other traced functions are nested
-deeper.  To tell each single process apart from any others that may be
-running concurrently, systemtap should also print the process ID in
-the line.
-
-<P>
-Systemtap provides a variety of such contextual data, ready for
-formatting.  They usually appear as function calls within the handler,
-like you already saw in Figure&nbsp;<A HREF="node2.html#fig:strace-open">1</A>.  See the
-<code>stapfuncs</code> man page for those functions and more defined in the
-tapset library, but here's a sampling:
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>tid()</code></TD>
-<TD ALIGN="LEFT">The id of the current thread.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>pid()</code></TD>
-<TD ALIGN="LEFT">The process (task group) id of the current thread.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>uid()</code></TD>
-<TD ALIGN="LEFT">The id of the current user.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>execname()</code></TD>
-<TD ALIGN="LEFT">The name of the current process.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>cpu()</code></TD>
-<TD ALIGN="LEFT">The current cpu number.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>gettimeofday_s()</code></TD>
-<TD ALIGN="LEFT">Number of seconds since epoch.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>get_cycles()</code></TD>
-<TD ALIGN="LEFT">Snapshot of hardware cycle counter.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>pp()</code></TD>
-<TD ALIGN="LEFT">A string describing the probe point being currently handled.</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>probefunc()</code></TD>
-<TD ALIGN="LEFT">If known, the name of the function in which
-                     this probe was placed.</TD>
-</TR>
-</TABLE>
-
-<P>
-The values returned may be strings or numbers.  The <code>print()</code>
-built-in function accepts either as its sole argument.  Or, you can
-use the C-style <code>printf()</code> built-in, whose formatting argument
-may include <code>%s</code> for a string, <code>%d</code> for a number.
-<code>printf</code> and other functions take comma-separated arguments.
-Don't forget a <code>"\n"</code> at the end.
-
-<P>
-A particularly handy function in the tapset library is
-<code>thread_indent</code>.  Given an indentation delta parameter, it stores
-internally an indentation counter for each thread (<code>tid()</code>), and
-returns a string with some generic trace data plus an appropriate
-number of indentation spaces.  That generic data includes a timestamp
-(number of microseconds since the most recent initial indentation), a
-process name and the thread id itself.  It therefore gives an idea not
-only about what functions were called, but who called them, and how
-long they took.  Figure&nbsp;<A HREF="#fig:socket-trace">3</A> shows the finished
-script.  It lacks a call to the <code>exit()</code> function, so you need to
-interrupt it with <code>^C</code> when you want the tracing to stop.

-Pages of generic tracing text may give you enough information for
-exploring a system.  With systemtap, it is possible to analyze that
-data, to filter, aggregate, transform, and summarize it.  Different
-probes can work together to share data.  Probe handlers can use a rich
-set of control constructs to describe algorithms, with a syntax taken
-roughly from <code>awk</code>.  With these tools, systemtap scripts can
-focus on a specific question and provide a compact response: no
-<code>grep</code> needed.

-</H2>

-<P>
-Most systemtap scripts include conditionals, to limit tracing or other
-logic to those processes or users or <EM>whatever</EM> of interest.  The
-syntax is simple:
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>if (</code><EM>EXPR</EM><code>)</code> <EM>STATEMENT</EM> [<code>else</code> <EM>STATEMENT</EM><code>]</code></TD>
-<TD ALIGN="LEFT">if/else statement</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>while (</code><EM>EXPR</EM><code>)</code> <EM>STATEMENT</EM></TD>
-<TD ALIGN="LEFT">while loop</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>for (</code><EM>A</EM><code>;</code> <EM>B</EM><code>;</code> <EM>C</EM><code>)</code> <EM>STATEMENT</EM></TD>
-<TD ALIGN="LEFT">for loop</TD>
-</TR>
-</TABLE>
-
-<P>
-Scripts may use <code>break</code>/<code>continue</code> as in C.
-Probe handlers can return early using <code>next</code> as in <code>awk</code>.
-Blocks of statements are enclosed in <code>{</code> and <code>}</code>.  In
-systemtap, the semicolon (<code>;</code>) is accepted as a null statement
-rather than as a statement terminator, so is only rarely<A NAME="tex2html4"
-  HREF="footnode.html#foot363"><SUP>1</SUP></A>necessary.  Shell-style (<code>#</code>), C-style (<code>/* */</code>), and
-C++-style (<code>//</code>) comments are all accepted.
-
-<P>
-Expressions look like C or <code>awk</code>, and support the usual
-operators, precedences, and numeric literals.  Strings are treated as
-atomic values rather than arrays of characters.  String concatenation
-is done with the dot (<code>"a" . "b"</code>).  Some examples:
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>(uid() &gt; 100)</code></TD>
-<TD ALIGN="LEFT">probably an ordinary user</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>(execname() == "sed")</code></TD>
-<TD ALIGN="LEFT">current process is sed</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>(cpu() == 0 &amp;&amp; gettimeofday_s() &gt; 1140498000)</code></TD>
-<TD ALIGN="LEFT">after Feb. 21, 2006, on CPU 0</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>"hello" . " " . "world"</code></TD>
-<TD ALIGN="LEFT">a string in three easy pieces</TD>
-</TR>
-</TABLE>
-
-<P>
-Variables may be used as well.  Just pick a name, assign to it, and
-use it in expressions.  They are automatically initialized and
-declared.  The type of each identifier - string vs. number - is
-automatically inferred by systemtap from the kinds of operators and
-literals used on it.  Any inconsistencies will be reported as errors.
-Conversion between string and number types is done through explicit
-function calls.
-
-<P>
-
-<P>
-<TABLE CELLPADDING=3>
-<TR><TD ALIGN="RIGHT"><code>foo = gettimeofday_s()</code></TD>
-<TD ALIGN="LEFT">foo is a number</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>bar = "/usr/bin/" . execname()</code></TD>
-<TD ALIGN="LEFT">bar is a string</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>c++</code></TD>
-<TD ALIGN="LEFT">c is a number</TD>
-</TR>
-<TR><TD ALIGN="RIGHT"><code>s = sprint(2345)</code></TD>
-<TD ALIGN="LEFT">s becomes the string "2345"</TD>
-</TR>
-</TABLE>
-
-<P>
-By default, variables are local to the probe they are used in.  That
-is, they are initialized, used, and disposed of at each probe handler
-invocation.  To share variables between probes, declare them global
-anywhere in the script.  Because of possible concurrency (multiple
-probe handlers running on different CPUs), each global variable used
-by a probe is automatically read- or write-locked while the handler is
-running.

-Target variables</A>
-</H2>
-
-<P>
-A class of special ``target variables'' allow access to the probe
-point context.    In a symbolic
-debugger, when you're stopped at a breakpoint, you can print values
-from the program's context.  In systemtap scripts, for those probe
-points that match with specific executable point (rather than an
-asynchronous event like a timer), you can do the same.  To know which
-variables are likely to be available, you will need to be familiar
-with the kernel source you are probing.  In addition, you will need to
-check that the compiler has not optimized those values into
-unreachable nonexistence.
-
-<P>
-Let's say that you are trying to trace filesystem reads/writes to a
-particular device/inode.  From your knowledge of the kernel, you know
-that two functions of interest could be <code>vfs_read</code> and
-<code>vfs_write</code>.  Each takes a <code>struct file *</code> argument, inside
-which there is a <code>struct dentry *</code>, a <code>struct inode *</code>, and
-so on.  Systemtap allows limited dereferencing of such pointer chains.
-Two functions, <code>user_string</code> and <code>kernel_string</code>, can copy
-<code>char *</code> target variables into systemtap strings.
-Figure&nbsp;<A HREF="#fig:inode-watch">5</A> demonstrates one way to monitor a
-particular file (identifed by device number and inode number).  This
-example also demonstrates pasting numeric command-line arguments
-(<code>$1</code> etc.) into scripts.
