Constructor Detail

LinuxPtraceProc

public LinuxPtraceProc(Host host,
                       Proc parent,
                       ProcessIdentifier pid,
                       Stat stat)

Create a new detached process. RUNNING makes no sense here. Since PARENT could be NULL, also explicitly pass in the host.

LinuxPtraceProc

public LinuxPtraceProc(Task task,
                       ProcessIdentifier fork)

Create a new, definitely attached, definitely running fork of Task.

Method Detail

getMainTask

public Task getMainTask()

Specified by:

getMainTask in class Proc

Returns:

The main task for this process XXX: Rather than getting the main task and manipulating that, it should be possible to instead manipulate the proc - for instance asking the proc to notify of fork/exec/clone events. At present this is implemented by ProcBlockAction.

getAuxv

public Auxv[] getAuxv()

Description copied from class: Proc

The Process Auxiliary Vector.

Specified by:

getAuxv in class Proc

getMaps

public MemoryMap[] getMaps()

Specified by:

getCmdLine

public String[] getCmdLine()

Description copied from class: Proc

Return the Proc's command line argument list

Specified by:

getCmdLine in class Proc

getUID

public int getUID()

Description copied from class: Proc

Return the UID of the Proc.

Specified by:

getUID in class Proc

getGID

public int getGID()

Description copied from class: Proc

Return the GID of the Proc.

Specified by:

getGID in class Proc

getExeFile

public SysRootFile getExeFile()

Description copied from class: Proc

Return the SysRoot path of the program that this process is running.

Specified by:

getExeFile in class Proc

getStat

public Stat getStat()

If it hasn't already been read, read the stat structure.

getCommand

public String getCommand()

Description copied from class: Proc

Return the basename of the program that this process is running.

Specified by:

getCommand in class Proc

sendRefresh

public void sendRefresh()

Refresh the Proc.

Overrides:
