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

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
specifed 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 beng 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 ths 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
IFR opcode in StartOpCodeHandle.
3) EndOpCOde is not NULL, and no IFR opcodes in the
target form following a matching start opcode match
the first IFR opcode in EndOpCodeHandle.
@retval EFI_SUCCESS The matched form is updated by StartOpcode.
