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 to kill(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 return only after the signal handler has returned.RETURN VALUE
raise() returns 0 on success, and nonzero for failure.ATTRIBUTES

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
