explain_fstatvfs_or_die(3) Library Functions Manual explain_fstatvfs_or_die(3)

NAME
       explain_fstatvfs_or_die - get file system statistics and	report errors

SYNOPSIS
       #include	<libexplain/fstatvfs.h>
       void explain_fstatvfs_or_die(int	fildes,	struct statvfs *data);
       int explain_fstatvfs_on_error(int fildes, struct	statvfs	*data);

DESCRIPTION
       The  explain_fstatvfs_or_die  function  is used to call the fstatvfs(2)
       system call. On failure an explanation will be printed to  stderr,  ob-
       tained from the explain_fstatvfs(3) function, and then the process ter-
       minates by calling exit(EXIT_FAILURE).

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

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

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

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

       The  explain_fstatvfs_on_error function always returns the value	return
       by the wrapped fstatvfs(2) system call.

EXAMPLE
       The explain_fstatvfs_or_die function is intended	to be used in a	 fash-
       ion similar to the following example:
	      explain_fstatvfs_or_die(fildes, data);
