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) system 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,
       obtained 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);

SEE ALSO
