PRESET_MAPS(3PROC) Process Control Library Functions PRESET_MAPS(3PROC)

NAME


Preset_maps - reset memory mapping data after exec

LIBRARY


Process Control Library (libproc, -lproc)

SYNOPSIS


#include <libproc.h>

void
Preset_maps(struct ps_prochandle *P);

DESCRIPTION


The Preset_maps() function resets all of the mapping data, cached symbol
tables, debug information, CTF, and more in the process handle P. The map
information will rebuild itself on the execution of another libproc(3LIB)
function that requires the information. This function should be called any
time after a process handle performs an exec(2). As such, this interface
is only relevant to the manipulation of live processes and not core files
or ELF files. For more information, see the PROGRAMMING NOTES section in
libproc(3LIB).

INTERFACE STABILITY


Uncommitted

MT-LEVEL
See LOCKING in libproc(3LIB).
