Detailed Description

The data structure passed to all syntax and AST callback functions, both rule and UDT.

It has been convenient to use a single data structure and function prototype for all callback functions, whether rule or UDT callback, whether syntax or semantic analysis. However, the variables in the callback data structure have slightly different meanings in each case. See APG_CALLBACK for the details about the different types of usage.
