Function Documentation

int explain_timerfd_create_on_error	(	int	clockid,
		int	flags
	)

The explain_timerfd_create_on_error function is used to call the timerfd_create(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_timerfd_create(3) function.

Parameters:

clockid	The clockid, exactly as to be passed to the timerfd_create(2) system call.
flags	The flags, exactly as to be passed to the timerfd_create(2) system call.

Returns:

The value returned by the wrapped timerfd_create(2) system call.

Example:

This function is intended to be used in a fashion similar to the following example:

 int result = explain_timerfd_create_on_error(clockid, flags);
 if (result < 0)
 {
     ...cope with error
     ...no need to print error message
 }
