  29 .Sh DESCRIPTION
  30 The
  31 .Fn Psetfault
  32 function sets the fault tracing flags on the process handle
  33 .Fa P
  34 to
  35 .Fa set .
  36 It replaces any existing fault tracing flags on the process.
  37 These flags indicate which faults cause execution of the thread to stop.
  38 Allowing another tool, such as a debugger, to act upon the process.
  39 For more information on faults and the
  40 .Sy fltset_t
  41 structure see the
  42 .Sy PCSFAULT
  43 section in
  44 .Xr proc 4 .
  45 The current fault set for the process may be obtained through the
  46 .Xr Pfault 3PROC
  47 function.
  48 .Pp
  49 Note, only active processes may have their fault set updated.
  50 Process handles that refer to core files, zombie processes, and files do not
  51 have fault tracing flags and this function is a no-op on them.
