NAME

explain_fpathconf_or_die - get file configuration and report errors

SYNOPSIS

#include <libexplain/fpathconf.h>
long explain_fpathconf_or_die(int fildes, int name);

DESCRIPTION

The explain_fpathconf_or_die function is used to call the fpathconf(3) system call. On failure an explanation will be printed to stderr, obtained from explain_fpathconf(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:

long result = explain_fpathconf_or_die(fildes, name);

	fildes		The fildes, exactly as to be passed to the fpathconf(3) system call.
	name		The name, exactly as to be passed to the fpathconf(3) system call.

Returns:

This function only returns on success, see fpathconf(3) for more information. On failure, prints an explanation and exits.
