99 @param[in] Request A null-terminated Unicode string in
100 <ConfigRequest> format.
101 @param[out] Progress On return, points to a character in the Request
102 string. Points to the string's null terminator if
103 request was successful. Points to the most recent
104 '&' before the first failing name/value pair (or
105 the beginning of the string if the failure is in
