MLReady()
 Usage
• int MLReady(MLINK link) tests whether there is data ready to be read from link.
Notes
• 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 Section 2.13.14.
