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

NAME

Pupdate_maps - update address space mappings

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

void
Pupdate_maps(struct ps_prochandle *P);

DESCRIPTION

The Pupdate_maps() function is used to verify that all of the cached
mappings in the process P are still valid and update the cached data
with any new information. This is generally called in response to
activity by the run-time link-editor. In general, the libproc library
takes care of managing the need to call this function; however,
debuggers, introspection tools, and others that are interposing on rtld
activity or other actions, may need to call this function. Note that
the Pupdate_maps() function is only meaningful for active processes.
It will do nothing on process handles that refer to core files, zombie
processes, and ELF objects.

INTERFACE STABILITY

Uncommitted
