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(4).

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.
