RAISE(3C) Standard C Library Functions RAISE(3C)

raise - send a signal to the executing thread

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

The raise() function sends the signal sig to the executing thread. If a signal handler is called, the raise function does not return until after the signal handler returns.

The effect of the raise function is equivalent to calling:

pthread_kill(pthread_self(), sig);

See the pthread_kill(3C) manual page for a detailed list of failure conditions and the signal.h(3HEAD) manual page for a list of signals.

Upon successful completion, 0 is returned. Otherwise, −1 is returned and errno is set to indicate the error.
