Question

I am a n00b to Linux. I am trying to understand the source code of a large C++ project
that includes a bunch of other headers and such.

In one of the main files, I see a bunch of function calls, but I don’t see the defintion in the file itself, so its obviously getting included from somewhere else.

I am looking for a way to search for the file or the place where the function is actually defined. Is there a way to do that? Please help. I am using Linux as I mentioned.

You can start with a command like

find . -name '*.[ch]*' | xargs grep some_search_term

For more advanced searching, you should consider looking into cscope or ctags.
