-\r
- Arguments:\r
- ImageBlock - Points to the beginning of a series of image blocks stored in order.\r
- ImageId - If input ImageId is 0, output the image id of the EFI_HII_IIBT_END_BLOCK;\r
- else use this id to find its corresponding image block address.\r
-\r
- Returns:\r
- The image block address when input ImageId is not zero; otherwise return NULL.\r
