NAME¶
raise - send a signal to the callerSYNOPSIS¶
#include <signal.h>int raise(int sig);
DESCRIPTION¶
The raise() function sends a signal to the calling process or thread. In a single-threaded program it is equivalent tokill(getpid(), sig);
In a multithreaded program it is equivalent to
pthread_kill(pthread_self(), sig);
If the signal causes a handler to be called, raise() will only return after the signal handler has returned.
RETURN VALUE¶
raise() returns 0 on success, and nonzero for failure.CONFORMING TO¶
C89, C99, POSIX.1-2001.NOTES¶
Since version 2.3.3, glibc implements raise() by calling tgkill(2), if the kernel supports that system call. Older glibc versions implemented raise() using kill(2).SEE ALSO¶
