Re: [Ctool-develop] using ctool as a library

[Shaun F. <fli...@so...>]

Stefan,

The best example to look at is probably the code that prints out the  
AST.  This starts at:
	operator<<(std::ostream& out, const TransUnit& tu)
in project.cpp

Each translation unit is composed of a list of statements, an hierarchy  
of C++ classes for each type (for, while, expression, etc).  Each of  
the statements has members in it that give pointers to the expressions  
it uses, or in some cases, the statement required.

Most of the members of the AST are public, you can just reach in and  
grab what you need.

Thanks,
Shaun
