The PiXCL Extension Command API

PiXCL is an extendable language, and there is an easy to understand means for C/C++ programmers to produce extension command set DLLs (PlugIns is another common name for this sort of file) to support, for example

• special hardware that has its own libraries
  

• third party libraries
  
• more custom dialogs and controls

All the necessary information to get access to the internal data structures in PiXCL is provided, along with a sample project in Visual C/C++.
