.Dd May 11, 2016 .Dt PSETSIGNAL 3PROC .Os .Sh NAME .Nm Psetsignal .Nd set signal tracing flags .Sh SYNOPSIS .Lb libproc n libproc.h .Ft void .Fo Psetsignal .Fa "struct ps_prochandle *P" .Fa "const sigset_t *set" .Fc .Sh DESCRIPTION The .Fn Psetsignal function sets the signal tracing flags for the process handle .Fa P to .Fa set . The call to .Fn Psetsignal replaces any existing signal tracing flags entirely with .Fa 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 .Sy PCSTRACE section in .Xr proc 4 .

p The .Fa set argument may be manipulated with the standard signal set manipulation functions such as .Xr sigaddset 3C , .Xr sigdelset 3C , and others which may all be found in .Xr sigsetops 3C .

p 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. .Sh INTERFACE STABILITY .Sy Uncommitted .Sh MT-LEVEL See .Sy LOCKING in .Xr libproc 3LIB . .Sh SEE ALSO .Xr sigsetops 3C , .Xr signal.h 3HEAD , .Xr libproc 3LIB , .Xr Psignal 3PROC , .Xr proc 4
