WSMain (C Function)

sets up communication between an external program started using Install and the Wolfram Language.

Details

  • The code for WSMain() is generated automatically by mprep or mcc.
  • WSMain() opens a WSTP connection using the parameters specified in argv, then goes into a loop waiting for CallPacket objects to arrive from the Wolfram Language.
  • WSMain() internally calls WSOpenArgcArgv().
  • WSMain() is declared in the WSTP header file wstp.h.
