There is no standard way in C to parse config files. Several libraries have sprung up to solve the problem, but perhaps that is overkill for what should be a simple operation.
Presenting: cfg_parse – a compile-in solution for reading key-value pairs from file(s), looking up settings, and writing a config file back to disk. I could write more about it, but the included main.c shows all the functionality.
