Scol

h1. Basis of a new plugin (on MS Windows)

All Scol types and functions are defined in the file header "scol.h", we make these features available including this file.

<pre>

#include <scol.h>

</pre>

To initialize the Scol virtual machine, you must add the following line (the variable must be called absolutely "ww ", the latter being used by all functions of the SDK).

<pre>

//!Scol machine declaration for MM macros

cbmachine ww;

</pre>

Each plugin needs a function of loading and unloading. These functions are called by the Scol virtual machine, they have a signature set.

<pre>

/*! 

 * \brief Starting point of the DLL

 */

 extern "C" __declspec (dllexport) 

 int ScolLoadPlugin(mmachine m, cbmachine w)

 {

       // Initializing SDK

 	SCOLinitplugin(w);

 	// Get Scol window handle (for message callback)

 	HScol = (HWND)SCgetExtra("hscol");

 	// Display debug message

 	MMechostr(MSKDEBUG,"Loading Template DLL ...\n");	

 	return 0; 

 }

 /*! 

 * \brief Ending point of the DLL							                

 */

 extern "C" __declspec (dllexport)

 int ScolUnloadPlugin()

 {

 	// Display debug messages

 	MMechostr(MSKDEBUG, "Template DLL CLOSED...\n\n" );

 	return 0;

 }

</pre>

To add the plugin to the environment Scol must map the name of the functions of loading and unloading in the file "usm.ini"

<pre>

plugin plugins/template.dll

</pre>
