| typedef EFI_STATUS(EFIAPI * EFI_HII_DATABASE_UPDATE_PACK) (IN CONST EFI_HII_DATABASE_PROTOCOL *This, IN EFI_HII_HANDLE Handle, IN CONST EFI_HII_PACKAGE_LIST_HEADER *PackageList) |
This function updates the existing package list (which has the specified Handle) in the HII databases, using the new package list specified by PackageList. The update process has the following steps: Collect all the package types in the package list specified by PackageList. A package type consists of the Type field of EFI_HII_PACKAGE_HEADER and, if the Type is EFI_HII_PACKAGE_TYPE_GUID, the Guid field, as defined in EFI_HII_PACKAGE_GUID_HEADER. Iterate through the packages within the existing package list in the HII database specified by Handle. If a package's type matches one of the collected types collected in step 1, then perform the following steps:
| This | A pointer to the EFI_HII_DATABASE_PROTOCOL instance. |
| Handle | The handle that was registered to the data that is requested for removal. |
| PackageList | A pointer to an EFI_HII_PACKAGE_LIST package. |
