DESCRIPTION

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.

LIMITATIONS

Comments in the config file are stripped on input and not preserved on write. Lookup keys are case-insensitive and may not contain the equals ('=') character. All config files are expected to contain only ASCII characters: UTF-8 or other wchar encodings are not supported.

cfg_parse structure is internally implemented as a singly-linked list. This means that many operations take O(n) time to complete (lookup, set/update, delete, etc.)

It is not recommended to store a very large number of items in the structure if you need high-performance lookup. Of course, if your config file is complex enough to cause performance issues, this library is probably not for you - switch to XML or JSON or similar.
