raise(3C)

NAME
     raise - send signal to executing program

SYNOPSIS
     #include <signal.h>

     int raise (int sig);

DESCRIPTION
     raise sends the signal sig to the calling thread.  This is functionally
     equivalent to calling pthread_kill(pthread_self(), sig).

SEE ALSO
     kill(2), pthread_kill(3P), signal(2), sigaction(2).

DIAGNOSTICS
     raise returns zero if the signal was successfully sent, -1 and errno is
     set to indicate the error.  See kill(2) for possible errors.
