parsing ".h subset" of c

Hi, a small problem for compiler experts... I don't know much
about compilers myself.


I need a c-parser which parses ".h subset of c", namely
c-files containing usual header declarations such as
type definitions (typedef etc), macros (#define with or
without parameters) and procedure signatures. (No problem if
whole c is parsed).


>From given input parser should output
- all identifiers declared in file and identifier types
- all referred identifers and reference types


For example: in file foo.h is a procedure signature


extern int foobar(int arg1, some_type_t *arg2);


>From this input parser should produce information that
file foo.h
defines identifier
'foobar' of type 'procedure'
and refers to identifiers
'arg1' of type 'int *'
'arg2' of type 'some_type_t *'


I guess there are pd-tools which can be used to get this information.
Any suggestions, what tool(s) and how could be used ?
