13 raise — send a signal to the executing process

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

21 The functionality described on this reference page is aligned with the
22 ISO C standard. Any conflict between the requirements described here
23 and the ISO C standard is unintentional. This volume of POSIX.1‐2008
24 defers to the ISO C standard.
25
26 The raise() function shall send the signal sig to the executing thread
27 or process. If a signal handler is called, the raise() function shall
28 not return until after the signal handler does.
29
30 The effect of the raise() function shall be equivalent to calling:
31
32 pthread_kill(pthread_self(), sig);
33
35 Upon successful completion, 0 shall be returned. Otherwise, a non-zero
36 value shall be returned and errno shall be set to indicate the error.
37
39 The raise() function shall fail if:
40
41 EINVAL The value of the sig argument is an invalid signal number.
