Setting up i2c on Raspberry Pi for C?

I'm setting up i2c for an Application written in C, but I've not been able to find any how-to's for it. I'm running a model-b Raspberry Pi on Debian 6 with LXDE. Can anybody show me how to set up i2c so I can use it in a C Application?

Thanks for any help in advance

Solution

I've been looking for similar information and I found a couple of i2c tutorials, one in adafruit tutorials and the other in Guy Carpenter's Gaugette blog. I'm not yet at the stage of actually using it so I can't vouch for their completeness but they seem to be a good start.
