4157 This function updates a form that has previously been registered with the HII \r

4159 \r
4160 The form to update is specified by Handle, FormSetGuid, and FormId. Binary \r
4161 comparisons of IFR opcodes are performed from the beginning of the form being \r
4162 updated until an IFR opcode is found that exactly matches the first IFR opcode \r
84213069 4163 specified by StartOpCodeHandle. The following rules are used to determine if\r
7e3bcccb
LG		 4164 an insert, replace, or delete operation is performed.\r
4165 \r
4166 1) If no matches are found, then NULL is returned. \r
4167 2) If a match is found, and EndOpCodeHandle is NULL, then all of the IFR opcodes\r
84213069
LG		 4168 from StartOpCodeHandle except the first opcode are inserted immediately after \r
4169 the matching IFR opcode in the form to be updated.\r
7e3bcccb 4170 3) If a match is found, and EndOpCodeHandle is not NULL, then a search is made \r
84213069 4171 from the matching IFR opcode until an IFR opcode exactly matches the first \r
7e3bcccb
LG		 4172 IFR opcode specified by EndOpCodeHandle. If no match is found for the first\r
4173 IFR opcode specified by EndOpCodeHandle, then NULL is returned. If a match\r
4174 is found, then all of the IFR opcodes between the start match and the end \r
4175 match are deleted from the form being updated and all of the IFR opcodes\r
84213069 4176 from StartOpCodeHandle except the first opcode are inserted immediately after \r
7e3bcccb 4177 the matching start IFR opcode. If StartOpCcodeHandle only contains one\r
84213069 4178 IFR instruction, then the result of this operation will delete all of the IFR\r
7e3bcccb

4185 @param[in] FormSetGuid The Formset GUID of the form to update. This\r
4186 is an optional parameter that may be NULL.\r
4187 If it is NULL, all FormSet will be updated.\r
4188 @param[in] FormId The ID of the form to update.\r
4189 @param[in] StartOpCodeHandle An OpCode Handle that contains the set of IFR \r
4190 opcodes to be inserted or replaced in the form.\r
4191 The first IFR instruction in StartOpCodeHandle \r
4192 is used to find matching IFR opcode in the \r
4193 form. \r
4194 @param[in] EndOpCodeHandle An OpCcode Handle that contains the IFR opcode\r
4195 that marks the end of a replace operation in\r
4196 the form. This is an optional parameter that\r
4197 may be NULL. If it is NULL, then an the IFR\r
4198 opcodes specified by StartOpCodeHandle are \r
4199 inserted into the form.\r
4200 \r
4201 @retval EFI_OUT_OF_RESOURCES No enough memory resource is allocated.\r
4202 @retval EFI_NOT_FOUND The following cases will return EFI_NOT_FOUND.\r
4203 1) The form specified by HiiHandle, FormSetGuid, \r
4204 and FormId could not be found in the HII Database.\r
4205 2) No IFR opcodes in the target form match the first\r
4206 IFR opcode in StartOpCodeHandle.\r
4207 3) EndOpCOde is not NULL, and no IFR opcodes in the \r
4208 target form following a matching start opcode match \r
