LinkReadyQ• LinkReadyQ[link] tests whether there is an expression ready to read from the specified MathLink connection. • link must be an active LinkObject, as returned by functions like LinkLaunch or Links. • If LinkReadyQ[link] returns True, then LinkRead[link] will not block under any normal circumstances. • If LinkReadyQ[link] returns False, then LinkRead[link] will block, and will not return until something becomes available to read on link. • LinkReadyQ[link] tests whether there is any data to read; it cannot determine whether the data represents a complete expression. • LinkReadyQ corresponds to the MathLink library function MLReady(). • See Section 2.13.6. • See also: LinkRead, LinkWrite, LinkInterrupt. • New in Version 3.
