       explain_stat_or_die - get file status and report errors

SYNOPSIS

       #include <libexplain/stat.h>
       void explain_stat_or_die(const char *pathname, struct stat *buf);

DESCRIPTION

       The  explain_stat_or_die  function  is used to call the stat(2) system call.  On failure an explanation will be printed to stderr, obtained
       from explain_stat(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_stat_or_die(pathname, buf);

       pathname
	       The pathname, exactly as to be passed to the stat(2) system call.

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

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

SEE ALSO

       stat(2) get file status

       explain_stat(3)
	       explain stat(2) errors
