MLReady() intMLReady(MLINKlink) tests whether there is data ready to be read from link. Analogous to the Mathematica function LinkReadyQ. MLReady() is often called in a loop as a way of polling a MathLink connection. MLReady() will always return immediately, and will not block. You need to call MLFlush() before starting to call MLReady(). See the Mathematica book: Section 2.12.14.
