call_scilab call_scilab is an interface which provides the ability to call Scilab engine from C/C++ code

## Description

Scilab offers the possibility to be called from a native (C/C++) application.

Thanks to this module, it is possible to call Scilab from C/C++ in order to interface Scilab's features from another code/application or to be able to interface Scilab's features from another language.

Since Scilab 5.2.0, all Scilab datatype can be handle by call_scilab. This is done thanks to API_Scilab

This help describes the features of the call_scilab API.

Note: The javasci module is based on call_scilab.

Note: old APIs (stackX.h) will not be available after Scilab 6.0 (included).

## Examples

    // A simple call_scilab example

    #include <stdio.h> /* stderr */

    #include "api_scilab.h" /* Provide functions to access to the memory of Scilab */
    #include "call_scilab.h" /* Provide functions to call Scilab engine */

    // Filename: simple_call_scilab.c

    int main(void)
    {
    /****** INITIALIZATION **********/
    #ifdef _MSC_VER
     if ( StartScilab(NULL,NULL,NULL) == FALSE )
    #else
     if ( StartScilab(getenv("SCI"),NULL,NULL) == FALSE )
    #endif
      {
       fprintf(stderr,"Error while calling StartScilab\n");
       return -1;
      }

    /****** ACTUAL Scilab TASKS *******/

     SendScilabJob("myMatrix=['sample','for the help']");
     SendScilabJob("disp(myMatrix);"); // Will display !sample  for the help  !
     SendScilabJob("disp([2,3]+[-44,39]);"); // Will display   - 42.    42.

    /****** TERMINATION **********/
     if ( TerminateScilab(NULL) == FALSE ) {
      fprintf(stderr,"Error while calling TerminateScilab\n");
      return -2;
     }
     return 0;
    }

## History

5.4.0 New methods added:

- `CallScilab.h` removed (was deprecated since Scilab 5.2.0). Replaced by `call_scilab.h`
- Function `int getLastErrorValue(void);` added. Returns the last error code generated by Scilab
- Function `const char* getLastErrorMessageSingle();` added. Returns the last error message generated by Scilab
- Remove deprecated functions in call_scilab.h: `C2F(readmat), C2F(creadmat), C2F(creadbmat), C2F(creadcmat), C2F(readchain), C2F(creadchain), C2F(creadchains), GetLengthStringMatrixByName, C2F(matptr), C2F(cmatptr), C2F(cmatcptr), C2F(cmatsptr), C2F(cmatbptr), getlengthchain`
