File format to store certain configurations

I would like to know which file format i can use to store(and easily parse and read) certain configuration items and th开发者_开发百科eir values. On eoption is INI file. Is there any other option like .opt file?

EDIT: I am using C language.

Look into XML. It's got implementations in many languages and is pretty easy to parse and create.

But a lot of it has to do with what language you're using.

Personally, I like to use XML files for configuration options. Most non-power users can understand them relatively easy enough and there are many libraries out there that make them super easy to parse.
