Function Documentation

void le_sig_DeleteAll

(

void

)

Removes all signal event handlers for the calling thread and cleans up any resources used for signal events. This should be called before the thread exits.

void le_sig_SetEventHandler	(	int	sigNum,
		le_sig_EventHandlerFunc_t	sigEventHandler
	)

Sets a signal event handler for the calling thread. Each signal can only have a single event handler per thread. The most recent event handler set will be called when the signal is received. sigEventHandler can be set to NULL to remove a previously set handler.

Note:

sigNum Cannot be SIGKILL or SIGSTOP or any program error signals: SIGFPE, SIGILL, SIGSEGV, SIGBUS, SIGABRT, SIGIOT, SIGTRAP, SIGEMT, SIGSYS.

Does not return on failure.

Parameters:

[in]	sigNum	Signal to set the event handler for. See parameter documentation in comments above.
[in]	sigEventHandler	Event handler to call when a signal is received.
