1298 current configuration string. If they are, they must appear
1299 after the current configuration. They must contain the same
1300 routing (GUID, NAME, PATH) as the current configuration string.
1301 They must have an additional description indicating the type of
1302 alternative configuration the string represents,
1303 "ALTCFG=<StringToken>". That <StringToken> (when
1304 converted from Hex UNICODE to binary) is a reference to a
1305 string in the associated string pack.
1306
1307 @param[in] This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
1308 @param[in] Request A null-terminated Unicode string in
1309 <ConfigRequest> format. Note that this
1310 includes the routing information as well as
1311 the configurable name / value pairs. It is
1312 invalid for this string to be in
1313 <MultiConfigRequest> format.
1314 @param[out] Progress On return, points to a character in the
1315 Request string. Points to the string's null
1316 terminator if request was successful. Points
1317 to the most recent "&" before the first
1318 failing name / value pair (or the beginning
1319 of the string if the failure is in the first
1320 name / value pair) if the request was not
1321 successful.
1322 @param[out] Results A null-terminated Unicode string in
1323 <ConfigAltResp> format which has all values
1324 filled in for the names in the Request string.
1325 String to be allocated by the called function.
1326
1327 @retval EFI_SUCCESS The Results string is filled with the
1328 values corresponding to all requested
1329 names.
1330 @retval EFI_OUT_OF_RESOURCES Not enough memory to store the
1331 parts of the results that must be
1332 stored awaiting possible future
1333 protocols.
1334 @retval EFI_INVALID_PARAMETER For example, passing in a NULL
1335 for the Request parameter
1336 would result in this type of
1337 error. In this case, the
1338 Progress parameter would be
1339 set to NULL.
1340 @retval EFI_NOT_FOUND Routing data doesn't match any
1341 known driver. Progress set to the
1342 first character in the routing header.
1343 Note: There is no requirement that the
1344 driver validate the routing data. It
1345 must skip the <ConfigHdr> in order to
1346 process the names.
1347 @retval EFI_INVALID_PARAMETER Illegal syntax. Progress set
1348 to most recent & before the
1349 error or the beginning of the
1350 string.
1351 @retval EFI_INVALID_PARAMETER Unknown name. Progress points
1352 to the & before the name in
1353 question. Currently not implemented.
