raise — send a signal to the caller
#include <signal.h>
int
raise( |
int sig); |
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.
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).
