FilledSmallSquareint MLFlush(MLINK link) flushes out any buffers containing data waiting to be sent on link.

FilledSmallSquare If you call MLNextPacket() or any of the MLGet*() functions, then MLFlush() will be called automatically.

FilledSmallSquare If you call MLReady(), then you need to call MLFlush() first in order to ensure that any necessary outgoing data has been sent.

FilledSmallSquare See The Mathematica Book: Section 2.12.14.
