Under Gtk+/Glib are there any utility functions, where we can read and write config File?

I have a config file in which I have key开发者_StackOverflows and values, like this:

key1=value1
key2=value2
key3=value3

So is there any utility functions in Gtk/Glib that can read this file and retrieve the value corresponds to key?

glib has a Key-value-file-parser. It supports a syntax similar to the better known INI files.

Here's a link to the documentation
