explain_fstatat_or_die(3)  Library Functions Manual  explain_fstatat_or_die(3)

NAME
       explain_fstatat_or_die  -  get file status relative to a	dir fd and re-
       port errors

SYNOPSIS
       #include	<libexplain/fstatat.h>
       void explain_fstatat_or_die(int fildes, const  char  *pathname,	struct
       stat *data, int flags);
       int  explain_fstatat_on_error(int  fildes, const	char *pathname,	struct
       stat *data, int flags);

DESCRIPTION
       The explain_fstatat_or_die function is used to call the fstatat(2) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_fstatat(3) function, and then the  process  terminates
       by calling exit(EXIT_FAILURE).

       The  explain_fstatat_on_error  function	is used	to call	the fstatat(2)
       system call. On failure an explanation will be printed to  stderr,  ob-
       tained  from  the explain_fstatat(3) function, but still	returns	to the
       caller.

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

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

       data    The data, exactly as to be  passed  to  the  fstatat(2)	system
	       call.

       flags   The  flags,  exactly  as	 to be passed to the fstatat(2)	system
	       call.

RETURN VALUE
       The explain_fstatat_or_die function only	returns	on  success,  see  fs-
       tatat(2)	 for  more  information. On failure, prints an explanation and
       exits, it does not return.

       The explain_fstatat_on_error function always returns the	 value	return
       by the wrapped fstatat(2) system	call.

EXAMPLE
       The explain_fstatat_or_die function is intended to be used in a fashion
       similar to the following	example:
	      explain_fstatat_or_die(fildes, pathname, data, flags);

SEE ALSO
       fstatat(2)
	       get file	status relative	to a directory file descriptor

       explain_fstatat(3)
	       explain fstatat(2) errors

       exit(2) terminate the calling process
