Psignal(struct ps_prochandle *P,
int which, int stop);
Psignal() function sets the signal tracing flag for the process handle P. If stop is non-zero it causes the process handle to stop threads that encounter the signal which. If stop is zero, then it disables tracing for the signal which.
The signal constants, representing valid values for
which, can be found in
signal.h(3HEAD). The signal
SIGKILL may not be stopped.
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 signal tracing flags. Calling this function on them is an error.
Psignal() function returns the previous disposition of the signal which. It returns 1 if it was set and 0 if not. Otherwise, -1 is returned and errno is set to indicate the error.
Psignal() function will fail if:
