Interface implementation with a program in С/С++

Let's consider how a C program should be prepared in order to make the WSTP protocol interaction available.

Firstly, as mentioned in the previous chapter, you need to prepare a special tm file that will describe all the data that will interact with Mathematica.

Secondly, the source code written in C should include the standard WSTP header file:

#include "wstp.h"

Note

This file is located in the C:\Program Files\Wolfram Research\Mathematica\10.1\SystemFiles\Links\WSTP\DeveloperKit\Windows-x86-64\CompilerAdditions\mldev64\include folder.

This file defines the following types:

WSLINK	A WSTP link object (analogous to LinkObject in the Wolfram Language)
WSMARK	A mark in a WSTP stream
WSENV	The WSTP library environment

All functions that return the int type—return 0 if their execution is not successful.

Thirdly, the external program should be ready to receive instructions from the Mathematica environment; that&apos...
