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.
raise() returns 0 on success, and nonzero for failure.
For an explanation of the terms used in this section, see

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).
