      int raise(  
int sig   


Signal to be raised.

Return Value

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


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.

Signal Meaning Default
SIGABRT Abnormal termination Terminates the calling program with exit code 3
SIGFPE Floating-point error Terminates the calling program
SIGILL Illegal instruction Terminates the calling program
SIGINT CTRL+C interrupt Terminates the calling program
SIGSEGV Illegal storage access Terminates the calling program
SIGTERM Termination request sent to the program Ignores the signal

If the argument is not a valid signal as specified above, the invalid parameter handler is invoked, as described in Parameter Validation. If not handled, the function sets errno to EINVAL and returns a nonzero value.
