57 * Name:	setup_temporary_directory
58 * Description:	create a temporary directory from specified components
59 *		and return full path to the directory created
60 * Arguments:	r_dirname - pointer to handle to string - on success,
61 *			the full path to the temporary directory created
62 *			is returned in this handle
63 *		a_tmpdir - pointer to string representing the directory into
64 *			which the new temporary directory should be created
65 *		a_suffix - pointer to string representing the 5-character
66 *			suffix to be used as the first part of the temporary
67 *			directory name invented
68 * Returns:	boolean_t
69 *			== B_TRUE - temporary directory created, path returned
70 *			== B_FALSE - failed to create temporary directory
71 *				'errno' is set to the failure reason
72 * NOTE:    	Any path returned is placed in new storage for the
73 *		calling function. The caller must use 'free' to dispose
74 *		of the storage once the path is no longer needed.
