29 Fills a target buffer with a 16-bit value, and returns the target buffer.
30
31 This function fills Length bytes of Buffer with the 16-bit value specified by
32 Value, and returns Buffer. Value is repeated every 16-bits in for Length
33 bytes of Buffer.

35 If Length > 0 and Buffer is NULL, then ASSERT().
36 If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().
37 If Buffer is not aligned on a 16-bit boundary, then ASSERT().
38 If Length is not aligned on a 16-bit boundary, then ASSERT().

40 @param Buffer Pointer to the target buffer to fill.
41 @param Length Number of bytes in Buffer to fill.
42 @param Value Value with which to fill Length bytes of Buffer.
