SYNOPSIS

#include <libexplain/fstat.h>
void explain_fstat_or_die(int fildes, struct stat *buf);

DESCRIPTION

The explain_fstat_or_die function is used to call the fstat (2) system call. On failure an explanation will be printed to stderr , obtained from explain_fstat (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_fstat_or_die(fildes, buf);

	fildes		The fildes, exactly as to be passed to the fstat (2) system call.
	buf		The buf, exactly as to be passed to the fstat (2) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits.
