The easiest example parser to look at is exuberent ctags in 
cedet/semantic/ectags/parse.el and neighboring files.

This basically shells out, parses the output of ctags which is very 
regular, and converts them into tag form.  These tags only provide a 
line number though, so you have to convert to a character to create a 
marker.

In C/C++ it is used to get tags from files not yet parsed by the regular 
semantic parser, so there is a way to convert between the two.  See the 
db.el next to parse.el.

If you want to use clang as a full replacement, then you would more 
likely do it as a replacement, the way some of the other languages are 
supported.

Good Luck
Eric
