Psetsignal —
set signal tracing flags
Process Control Library (libproc, -lproc)
#include
<libproc.h>
void
Psetsignal(
struct
ps_prochandle *P,
const sigset_t *set);
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.
