explain_statvfs_or_die(3)  Library Functions Manual  explain_statvfs_or_die(3)

NAME
       explain_statvfs_or_die -	get file system	statistics and report errors

SYNOPSIS
       #include	<libexplain/statvfs.h>
       void   explain_statvfs_or_die(const   char  *pathname,  struct  statvfs
       *data);
       int  explain_statvfs_on_error(const  char  *pathname,  struct   statvfs
       *data);

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

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

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

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

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

       The  explain_statvfs_on_error  function always returns the value	return
       by the wrapped statvfs(2) system	call.

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

	       get file	system statistics
