3184 @param This A pointer to the EFI_HII_CONFIG_ROUTING_PROTOCOL\r
3185 instance.\r
3186 @param ConfigResp A null-terminated Unicode string in <ConfigResp>\r
84f9a9ec 3187 format. It can be ConfigAltResp format string.\r
93e3992d 3188 @param Block A possibly null array of bytes representing the\r
3189 current block. Only bytes referenced in the\r
3190 ConfigResp string in the block are modified. If\r
3191 this parameter is null or if the *BlockSize\r
3192 parameter is (on input) shorter than required by\r
3193 the Configuration string, only the BlockSize\r
3194 parameter is updated and an appropriate status\r
3195 (see below) is returned.\r
3196 @param BlockSize The length of the Block in units of UINT8. On\r
3197 input, this is the size of the Block. On output,\r
3198 if successful, contains the index of the last\r
3199 modified byte in the Block.\r
3200 @param Progress On return, points to an element of the ConfigResp\r
3201 string filled in with the offset of the most\r
3202 recent '&' before the first failing name / value\r
3203 pair (or the beginning of the string if the\r
3204 failure is in the first name / value pair) or the\r
3205 terminating NULL if all was successful.\r
3206\r

3208 terminator at the end of the ConfigResp string.\r

3210 points to the first character of ConfigResp.\r
3211 @retval EFI_INVALID_PARAMETER Passing in a NULL for the ConfigResp or\r
3212 Block parameter would result in this type of\r
3213 error. Progress points to the first character of\r
3214 ConfigResp.\r

3216 value pair. Block is left updated and\r
