84f9a9ec 3196 <MultiConfigAltResp> format. It is <ConfigAltResp> format.\r

3198 routing portion of the ConfigResp string when\r
3199 retrieving the requested data. If Guid is NULL,\r
3200 then all GUID values will be searched for.\r

3212 retrieving the requested data. If this parameter\r
3213 is NULL, then the current setting will be\r
3214 retrieved.\r

3216 the function which contains the retrieved string\r
3217 as requested. This buffer is only allocated if\r
84f9a9ec 3218 the call was successful. It is <ConfigResp> format.\r
