function::sprint_backtrace — Return stack back trace as string
sprint_backtrace:string()
Returns a simple (kernel) backtrace. One line per address.
Includes the symbol name (or hex address if symbol
couldn't be resolved) and module name (if found). Includes the
offset from the start of the function if found, otherwise the
offset will be added to the module (if found, between
brackets). Returns the backtrace as string (each line terminated by
a newline character). Note that the returned stack will be
truncated to MAXSTRINGLEN, to print fuller and richer stacks use
print_backtrace
. Equivalent to sprint_stack(backtrace
),
but more efficient (no need to translate between hex strings and
final backtrace string).
