Function Documentation

void explain_link_or_die	(	const char *	oldpath,
		const char *	newpath
	)

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

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

 explain_link_or_die(oldpath, newpath);

Parameters:

oldpath	The oldpath, exactly as to be passed to the link(2) system call.
newpath	The newpath, exactly as to be passed to the link(2) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits, it does not return.
