I don't know about functions that can handle this, but look into string tokenizers.

aren't there any other useful functions, because it is used often and in many programs?

AFAIK there are none. And think it's a bit strange as well. getopt() exists for a long time, but general config file parser do not exist apparently...

You could copy some functions for it from a free software source.

One option that comes close may be to use XML config files and use a XML-parser library. But if your program is simple, this may be an overkill.

Check out mkxf86config from It contains two short functions: checkbootparam and getbootparam that are for parsing options from /proc/cmdline.
You can use those or modify to suit.
