 /**
+  
+  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.
