MathLink C Function

MLFlush()

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

MORE INFORMATION

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

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

MLFlush() returns 0 in the event of an error, and a nonzero value if the function succeeds.

Use MLError() to retrieve the error code if MLFlush() fails.

MLFlush() is declared in the MathLink header file mathlink.h.

    if(! MLPutString(lp, "Integrate[1/x^2, x]"))
