PSETSIGNAL(3PROC) Process Control Library Functions PSETSIGNAL(3PROC)
NAME
Psetsignal - set signal tracing flags
LIBRARY
Process Control Library (libproc, -lproc)
SYNOPSIS
#include <libproc.h> void Psetsignal(
struct ps_prochandle *P,
const sigset_t *set);
DESCRIPTION
The
Psetsignal() function sets the signal tracing flags for the process
handle
P to
set. The call to
Psetsignal() replaces any existing signal
tracing flags entirely with
set. The signal tracing flags determine which
signals, when received by a thread in the process, will cause that thread
to stop. For more information on the behavior of the signal tracing flags,
including which signals may be traced this way, see the
PCSTRACE section in
proc(5).
The
set argument may be manipulated with the standard signal set
manipulation functions such as
sigaddset(3C),
sigdelset(3C), and others
which may all be found in
sigsetops(3C).
Note, only active processes may have their signal tracing flags updated.
Process handles that refer to core files, zombie processes, and files do
not have fault tracing flags and this function is a no-op on them.
