Detailed Description

Conversion layer between the parser service and this plugin.

This plugin is written in C++, while the parser service is written in C.

The layer handles:

  • Copying between server and plugin memory. This is necessary on some platforms (e.g. Windows) where dynamicly linked libraries have their own heap.
  • Wrapping raw const char * in std::string classes.
