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) system 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,
       obtained 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 fstatfs(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);
