VCache_SwapBuffers

Given two cache block handles, this procedure swaps the buffers associated with the handles. The blocks must be owned by the same client and they must both be held. Uses EAX and flags.

• No return value; however, the Carry flag is cleared if the blocks are swapped. If the blocks are not swapped, the Carry flag is set.

On entry, ESI contains the handle of the first cache block.

On entry, EDI contains the handle of the second cache block.
