raise(3C)                      DG/UX R4.11MU05                     raise(3C)


NAME
       raise - send signal to program

SYNOPSIS
       #include <signal.h>

       int raise (int sig);

DESCRIPTION
       raise sends the signal sig to the executing program.

       raise returns zero if the operation succeeds. Otherwise, raise
       returns -1 and errno is set to indicate the error.  raise uses kill
       to send the signal to the executing program:

              kill(getpid(), sig);

       See kill(2) for a detailed list of failure conditions.  See signal(2)
       for a list of signals.
