◆ EFI_HII_DATE_UINT64

#define EFI_HII_DATE_UINT64 (   Year,
  Month,
  Day 
)     (UINT64)((Year & 0xffff) | ((Month & 0xff) << 16) | ((Day & 0xff) << 24))

Returns a UINT64 value that contains bit fields for Year, Month, and Day. The lower 16-bits of Year are placed in bits 0..15. The lower 8-bits of Month are placed in bits 16..23, and the lower 8-bits of Day are placed in bits 24..31. This format was selected because it can be easily translated to an EFI_HII_DATE structure in an EFI_IFR_TYPE_VALUE union.

Parameters
YearThe year value to be encoded.
MonthThe month value to be encoded.
DayThe day value to be encoded.
Returns
A 64-bit containing Year, Month, and Day.

)

Registers a list of packages in the HII Database and returns the HII Handle associated with that registration. If an HII Handle has already been registered with the same PackageListGuid and DeviceHandle, then NULL is returned. If there are not enough resources to perform the registration, then NULL is returned. If an empty list of packages is passed in, then NULL is returned. If the size of the list of package is 0, then NULL is returned.

The variable arguments are pointers that point to package headers defined by UEFI VFR compiler and StringGather tool.

◆ HiiUpdateForm()

EFI_STATUS EFIAPI HiiUpdateForm ( IN EFI_HII_HANDLE  HiiHandle,
IN EFI_GUID *FormSetGuid  OPTIONAL,
IN EFI_FORM_ID  FormId,
IN VOID *  StartOpCodeHandle,
IN VOID *EndOpCodeHandle  OPTIONAL 
)

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().

Parameters
[in]HiiHandleThe HII Handle of the form to update.
[in]FormSetGuidThe 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.
[in]FormIdThe ID of the form to update.
[in]StartOpCodeHandleAn 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.
[in]EndOpCodeHandleAn 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.
Return values
EFI_OUT_OF_RESOURCESNot enough memory resources are allocated.
EFI_NOT_FOUNDThe 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.
EFI_SUCCESSThe matched form is updated by StartOpcode.

◆ HiiValidateSettings()

BOOLEAN EFIAPI HiiValidateSettings ( IN CONST EFI_STRING Request  OPTIONAL)

Validate the current configuration by parsing the IFR opcode in HII form.

NULL request string support depends on the ExportConfig interface of HiiConfigRouting protocol in the UEFI specification.

Parameters
RequestA null-terminated Unicode string in <MultiConfigRequest> format. It can be NULL. If it is NULL, all current configurations for the entirety of the current HII database will be validated.
Return values
TRUEThe current configuration is valid.
FALSEThe current configuration is invalid.

Parameters
RequestA null-terminated Unicode string in <MultiConfigRequest> format. It can be NULL. If it is NULL, all current configuration for the entirety of the current HII database will be validated.
Return values
TRUECurrent configuration is valid.
FALSECurrent configuration is invalid.
