-Routine Description:
-
- Helper function called as part of the code needed
- to allocate the proper sized buffer for various
- EFI interfaces.
-
-Arguments:
-
- Status - Current status
-
- Buffer - Current allocated buffer, or NULL
-
- BufferSize - Current buffer size needed
-
-Returns:
-
- TRUE - if the buffer was reallocated and the caller
- should try the API again.
-
- FALSE - buffer could not be allocated and the caller
- should not try the API again.
