LinkWrite

LinkWrite[link,expr]

writes expr to the specified WSTP connection.

Details

  • 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 Wolfram Language kernel, EnterTextPacket["string"] enters the text of an input line, and EvaluatePacket[expr] sends an expression for evaluation.
