Using gcc to parse C++ sources

[Juergen Graf]

Hi gcc folks,

i plan to parse c++ source files in order to extract information about
function signatures and typedefs. After reading some pages of the gcc internals
documentation, i found out, that gcc uses an internal tree structure (tree.h)
to represent the parsed (c++) source files. This tree structure seems to be
able to satisfy my needs.

I want to modify/use the gcc to pass me this tree structure. My problem is,
that i don't know exactly where to start at and how this can be achieved in
the easiest way. Please can anybody drop me a hint.

Greets,
