explain_fstatfs_or_die(3)  Library Functions Manual  explain_fstatfs_or_die(3)

NAME
       explain_fstatfs_or_die -	get file system	statistics and report errors

SYNOPSIS
       #include	<libexplain/fstatfs.h>
       void explain_fstatfs_or_die(int fildes, struct statfs *data);
       int explain_fstatfs_on_error(int	fildes,	struct statfs *data);

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

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

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

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

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

       The  explain_fstatfs_on_error  function always returns the value	return
       by the wrapped fstatfs(2) system	call.

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