12 raise - send a signal to the executing process

15 #include <signal.h>
16
17 int raise(int sig);

21 The raise() function shall send the signal sig to the executing thread
22 or process. If a signal handler is called, the raise() function shall
23 not return until after the signal handler does.
24
25 If the implementation supports the Threads option, the effect of the
26 raise() function shall be equivalent to calling:
27
28
29 pthread_kill(pthread_self(), sig);
30
31 Otherwise, the effect of the raise() function shall be equivalent to
32 calling:
33
34
35 kill(getpid(), sig);
36
38 Upon successful completion, 0 shall be returned. Otherwise, a non-zero
39 value shall be returned and errno shall be set to indicate the error.
40
42 The raise() function shall fail if:
43
44 EINVAL The value of the sig argument is an invalid signal number.
