/*
 *  ======== uuid_uuid_to_string ========
 *  Purpose:
 *      Converts a dsp_uuid to an ANSI string.
 *  Parameters:
 *      uuid_obj:      Pointer to a dsp_uuid object.
 *      sz_uuid:    Pointer to a buffer to receive a NULL-terminated UUID
 *                  string.
 *      size:	    Maximum size of the sz_uuid string.
 *  Returns:
 *  Requires:
 *      uuid_obj & sz_uuid are non-NULL values.
 *  Ensures:
 *      Lenghth of sz_uuid is less than MAXUUIDLEN.
 *  Details:
 *      UUID string limit currently set at MAXUUIDLEN.
