static void usage

(

)

[static]

Give checkconf usage, and exit (1).

static char* fname_after_chroot	(	const char *	fname,
		struct config_file *	cfg,
		int	use_chdir
	)			[static]

convert a filename to full pathname in original filesys

Parameters:

	fname,:	the path name to convert. Must not be null or empty.
	cfg,:	config struct for chroot and chdir (if set).
	use_chdir,:	if false, only chroot is applied.

Returns:

pointer to static buffer which is: [chroot][chdir]fname
