explain_statfs_or_die(3)   Library Functions Manual   explain_statfs_or_die(3)

NAME
       explain_statfs_or_die - get file	system statistics and report errors

SYNOPSIS
       #include	<libexplain/statfs.h>
       void explain_statfs_or_die(const	char *pathname,	struct statfs *data);
       int explain_statfs_on_error(const char *pathname, struct	statfs *data);

DESCRIPTION
       The explain_statfs_or_die function is used to call the statfs(2)	system
       call. On	failure	an explanation will be	printed	 to  stderr,  obtained
       from the	explain_statfs(3) function, and	then the process terminates by
       calling exit(EXIT_FAILURE).

       The explain_statfs_on_error function is used to call the	statfs(2) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_statfs(3) function, but	still returns to the caller.

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

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

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

       The explain_statfs_on_error function always returns the value return by
       the wrapped statfs(2) system call.

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

SEE ALSO
       statfs(2)
	       get file	system statistics

       explain_statfs(3)
