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) system 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);
