| 861 | This function updates a form that has previously been registered with the HII \r | |
| 862 | Database. This function will perform at most one update operation.\r | |
| 863 | \r | |
| 864 | The form to update is specified by Handle, FormSetGuid, and FormId. Binary \r | |
| 865 | comparisons of IFR opcodes are performed from the beginning of the form being \r | |
| 866 | updated until an IFR opcode is found that exactly matches the first IFR opcode \r | |
| 867 | specifed by StartOpCodeHandle. The following rules are used to determine if\r | |
| 868 | an insert, replace, or delete operation is performed.\r | |
| 869 | \r | |
| 870 | 1) If no matches are found, then NULL is returned. \r | |
| 871 | 2) If a match is found, and EndOpCodeHandle is NULL, then all of the IFR opcodes\r | |
| 872 | from StartOpcodeHandle except the first opcode are inserted immediately after \r | |
| 873 | the matching IFR opcode in the form beng updated.\r | |
| 874 | 3) If a match is found, and EndOpCodeHandle is not NULL, then a search is made \r | |
| 875 | from the matching IFR opcode until an IFR opcode exatly matches the first \r | |
| 876 | IFR opcode specified by EndOpCodeHandle. If no match is found for the first\r | |
| 877 | IFR opcode specified by EndOpCodeHandle, then NULL is returned. If a match\r | |
| 878 | is found, then all of the IFR opcodes between the start match and the end \r | |
| 879 | match are deleted from the form being updated and all of the IFR opcodes\r | |
| 880 | from StartOpcodeHandle except the first opcode are inserted immediately after \r | |
| 881 | the matching start IFR opcode. If StartOpCcodeHandle only contains one\r | |
