explain_fstat_or_die - get file status and report errors

#include <libexplain/fstat.h>

void explain_fstat_or_die(int fildes, struct stat *buf);

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

fstat(2)
get file status
explain_fstat(3)
explain fstat(2) errors
exit(2)
terminate the calling process
