LinkRead

LinkRead[link]
reads one expression from the specified MathLink connection.
LinkRead[link, h]
wraps h around the expression read before evaluating it.
  • 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.
