Pupdate_syms —
update cached symbol tables
Process Control Library (libproc, -lproc)
#include
<libproc.h>
void
Pupdate_syms(
struct
ps_prochandle *P);
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.
