+
+ This function returns a list of the package handles of the
+ specified type that are currently active in the HII database. The
+ pseudo-type EFI_HII_PACKAGE_TYPE_ALL will cause all package
+ handles to be listed.
+ If HandleBufferLength is NULL, then ASSERT.
+ If HandleBuffer is NULL, the ASSERT.
+ If PackageType is EFI_HII_PACKAGE_TYPE_GUID and PackageGuid is
+ NULL, then ASSERT.
+ If PackageType is not EFI_HII_PACKAGE_TYPE_GUID and PackageGuid is not
+ NULL, then ASSERT.
+
+
+ @param PackageType Specifies the package type of the packages
+ to list or EFI_HII_PACKAGE_TYPE_ALL for
+ all packages to be listed.
+
+ @param PackageGuid If PackageType is
+ EFI_HII_PACKAGE_TYPE_GUID, then this is
+ the pointer to the GUID which must match
+ the Guid field of
+ EFI_HII_PACKAGE_GUID_HEADER. Otherwise, it
+ must be NULL.
+
+ @param HandleBufferLength On output, the length of the handle buffer
+ that is required for the handles found.
+
+ @param HandleBuffer On output, an array of EFI_HII_HANDLE instances returned.
+ The caller is responcible to free this pointer allocated.
+
+ @retval EFI_SUCCESS The matching handles are outputed successfully.
+ HandleBufferLength is updated with the actual length.
+ @retval EFI_OUT_OF_RESOURCES Not enough resource to complete the operation.
+ @retval EFI_NOT_FOUND No matching handle could not be found in database.
