* Name: sig_raise
|
|
*
|
|
* Description:
|
|
* The raise() function sends the signal signo to the executing thread or
|
|
* process. If a signal handler is called, the raise() function does not
|
|
* return until after the signal handler does.
|
|
*
|
|
* If the implementation supports the Threads option, the effect of the
|
|
* raise() function is equivalent to calling:
|
|
*
|
|
* pthread_kill(pthread_self(), signo);
|
|
*
|
|
* except that on failures, -1 (ERROR) is returned and the errno() variable
|
|
* is set accordingly. Otherwise, the effect of the raise() function is
|
|
* equivalent to calling:
|
|
*
|
|
* kill(getpid(), signo)
|
|
*
