.Sh SYNOPSIS
.Lb libproc
.In libproc.h
.Ft void
.Fo Psetfault
.Fa "struct ps_prochandle *P"
.Fa "const fltset_t *set"
.Fc
.Sh DESCRIPTION
The
.Fn Psetfault
function sets the fault tracing flags on the process handle
.Fa P
to
.Fa set .
It replaces any existing fault tracing flags on the process.
These flags indicate which faults cause execution of the thread to stop.
Allowing another tool, such as a debugger, to act upon the process.
For more information on faults and the
.Sy fltset_t
structure see the
.Sy PCSFAULT
section in
.Xr proc 4 .
The current fault set for the process may be obtained through the
.Xr Pfault 3PROC
function.
.Pp
Note, only active processes may have their fault set 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.
