  • Analogous to the Wolfram Language 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 must call MLFlush() before calling MLReady().
  • MLReady() returns 0 if the link has no data to read and a nonzero value if the link does have data.
  • MLReady() is declared in the MathLink header file mathlink.h.
