  13   15  DESCRIPTION
  14   16       The Psignal() function sets the signal tracing flag for the process
  15   17       handle P.  If stop is non-zero it causes the process handle to stop
  16   18       threads that encounter the signal which.  If stop is zero, then it
  17   19       disables tracing for the signal which.

  18   20  
  19   21       The signal constants, representing valid values for which, can be found
  20   22       in signal.h(3HEAD.) The signal SIGKILL may not be stopped.
  21   23  
  22   24       Note, only active processes may have their signal tracing flags updated.
  23   25       Process handles that refer to core files, zombie processes, and files do
  24   26       not have signal tracing flags.  Calling this function on them is an
  25   27       error.
  26   28  
  27   29  RETURN VALUES
  28   30       Upon successful completion, the Psignal() function returns the previous
  29   31       disposition of the signal which.  It returns 1 if it was set and 0 if
  30   32       not.  Otherwise, -1 is returned and errno is set to indicate the error.
  31   33  
  32   34  ERRORS
  33   35       The Psignal() function will fail if:
  34   36  
  35   37       EINVAL             which is SIGKILL and stop is non-zero .
  36   38  
  37   39                          which is not a valid signal.
  38   40  
  39   41       ENOENT             P does not correspond to an active process.
