FilledSmallSquareLinkRead[link] reads one expression from the specified MathLink connection.

FilledSmallSquareLinkRead[link, h] wraps h around the expression read before evaluating it.

FilledSmallSquarelink must be an active LinkObject, as returned by functions like LinkLaunch or Links.

FilledSmallSquareLinkRead will wait until it has read a complete expression before returning.

FilledSmallSquare You can test whether an expression is ready to be read from a particular link using LinkReadyQ.
