Note

Do not use this method to shut down a Windows Store app, except in testing or debugging scenarios. Programmatic or UI ways to close a Windows Store app are not permitted according to Section 3.6 of the Windows 8 app certification requirements. For more information, see Application lifecycle (Windows Store apps).

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.

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.

Requirements

Routine	Required header
raise	<signal.h>
