+  This function updates a form that has previously been registered with the HII 

+  Database.  This function will perform at most one update operation.

+    

+  The form to update is specified by Handle, FormSetGuid, and FormId.  Binary 

+  comparisons of IFR opcodes are performed from the beginning of the form being 

+  updated until an IFR opcode is found that exactly matches the first IFR opcode 

+  specified by StartOpCodeHandle.  The following rules are used to determine if

+  an insert, replace, or delete operation is performed:

+  

+  1) If no matches are found, then NULL is returned.  

+  2) If a match is found, and EndOpCodeHandle is NULL, then all of the IFR opcodes

+     from StartOpCodeHandle except the first opcode are inserted immediately after 

+     the matching IFR opcode in the form to be updated.

+  3) If a match is found, and EndOpCodeHandle is not NULL, then a search is made 

+     from the matching IFR opcode until an IFR opcode exactly matches the first 

+     IFR opcode specified by EndOpCodeHandle.  If no match is found for the first

+     IFR opcode specified by EndOpCodeHandle, then NULL is returned.  If a match

+     is found, then all of the IFR opcodes between the start match and the end 

+     match are deleted from the form being updated and all of the IFR opcodes

+     from StartOpCodeHandle except the first opcode are inserted immediately after 

+     the matching start IFR opcode.  If StartOpCcodeHandle only contains one

+     IFR instruction, then the result of this operation will delete all of the IFR

+     opcodes between the start end matches.

+

+  If HiiHandle is NULL, then ASSERT().

+  If StartOpCodeHandle is NULL, then ASSERT().

+

+  @param[in]  HiiHandle          The HII Handle of the form to update.

+  @param[in]  FormSetGuid        The Formset GUID of the form to update.  This

+                                 is an optional parameter that may be NULL.

+                                 If it is NULL, all FormSet will be updated.

+  @param[in]  FormId             The ID of the form to update.

+  @param[in]  StartOpCodeHandle  An OpCode Handle that contains the set of IFR 

+                                 opcodes to be inserted or replaced in the form.

+                                 The first IFR instruction in StartOpCodeHandle 

+                                 is used to find matching IFR opcode in the 

+                                 form. 

+  @param[in]  EndOpCodeHandle    An OpCcode Handle that contains the IFR opcode

+                                 that marks the end of a replace operation in

+                                 the form.  This is an optional parameter that

+                                 may be NULL.  If it is NULL, then the IFR

+                                 opcodes specified by StartOpCodeHandle are 

+                                 inserted into the form.

+  

+  @retval EFI_OUT_OF_RESOURCES   Not enough memory resources are allocated.

+  @retval EFI_NOT_FOUND          The following cases will return EFI_NOT_FOUND:

+                                 1) The form specified by HiiHandle, FormSetGuid, 

+                                 and FormId could not be found in the HII Database.

+                                 2) No IFR opcodes in the target form match the first

+                                 3) EndOpCOde is not NULL, and no IFR opcodes in the

+                                 the first IFR opcode in EndOpCodeHandle.
