BUILT-IN MATHEMATICA SYMBOL
LinkWrite
LinkWrite[link, expr]
writes expr to the specified MathLink connection.
- link must be an active LinkObject, as returned by functions like LinkLaunch or Links.
- You can use LinkWrite[link, Unevaluated[expr]] to write expr to the link without evaluating it.
- The head of expr will often be a packet that specifies how expr should be processed by the program which receives it.
- When LinkWrite is used to send data to a Mathematica kernel, EnterTextPacket["string"] enters the text of an input line, and EvaluatePacket[expr] sends an expression for evaluation.
Launch a subsidiary Mathematica kernel process:
| Out[1]= |  |
Read the first packet:
| Out[2]= |  |
Write the expression 
to the link without evaluating it:
Read the result:
| Out[4]= |  |
Close the link:
