Function Documentation

void explain_truncate_or_die	(	const char *	pathname,
		off_t	length
	)

The explain_truncate_or_die function is used to call the truncate(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_truncate(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

Parameters:

pathname	The pathname, exactly as to be passed to the truncate(2) system call.
length	The length, exactly as to be passed to the truncate(2) system call.

Returns:

This function only returns on success, see truncate(2) for more information. On failure, prints an explanation and exits, it does not return.

Example:

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

 explain_truncate_or_die(pathname, length);
