BUILT-IN MATHEMATICA SYMBOL
LinkRead
LinkRead[link]
reads one expression from the specified MathLink connection.
LinkRead[link, h]
wraps h around the expression read before evaluating it.
- link must be an active LinkObject, as returned by functions like LinkLaunch or Links.
- LinkRead will wait until it has read a complete expression before returning.
- You can test whether an expression is ready to be read from a particular link using LinkReadyQ.
- You can use LinkRead[link, Hold] to get an expression from a link without evaluating it.
