explain_link_or_die - make a new name for a file and report errors

SYNOPSIS

#include <libexplain/link.h>
void explain_link_or_die(const char *oldpath, const char *newpath);

DESCRIPTION

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 explain_link (3), 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);

	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.
