Question

Languages like Python, MATLAB, E-Lisp have this nice facility for doc-strings.
With this feature using just a few keystrokes in the terminal, you can fetch the documentations of the functions / module you have written and imported into your code.

Now is there any “technique” (library, Editor tricks , whatever to ) to get a similar facility in
C++ / C. Suppose I include the documentation of the function within the source file at
the head of the function,
then I would like to type a command like getinfo at the terminal. (something
like a man page)

I know such a ‘man’ facility exists for many C functions, but the documentation for these functions are written in separate text files from the source code. I would like the
documentation to be in-place

Answer 1

You can use something like doxygen. It has support for generating man pages, among other formats.
