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

NAME

Pupdate_syms - update cached symbol tables

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

void
Pupdate_syms(struct ps_prochandle *P);

DESCRIPTION

The Pupdate_syms() function is used to update all of the cached symbol
tables in the process handle P: updating, invalidating, and caching new
symbol tables as appropriate for functions such as Psymbol_iter(3PROC).
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 may need to call this
function. Note that the Pupdate_syms() function is only meaningful for
active processes. It will do nothing on process handles that refer to
core files, zombie processes, and ELF objects.
