raise

Sends a signal to the executing program.

int raise(
   int sig 
);

Parameters

  • sig
    Signal to be raised.

Return Value

If successful, raise returns 0. Otherwise, it returns a nonzero value.

Remarks

The raise function sends sig to the executing program. If a previous call to signal has installed a signal-handling function for sig, raise executes that function. If no handler function has been installed, the default action associated with the signal value sig is taken, as follows.
