NAME

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);
The oldpath, exactly as to be passed to the link(2) system call.
The newpath, exactly as to be passed to the link(2) system call.
This function only returns on success. On failure, prints an explanation and exits.
