programming Ir communication with C

I am interested in programming the Irda protocol in C. I have already downloaded the specifications for each of the layers contained in the protocol (from the Irda.Org web site), and coded a little.

But now I am stuck, concerning issues such as, the code behind frames (the format that data is packaged in when transferring data between two Irda devices).

Is anybody able to help, or suggests where I may be able to get source code from?.

You could use arrays or structures to contain the frames. You will need to write code for retrieving and sending frames, such could be done by writing data to ports. Detecting if data arrives at a port could be done by polling, interrupts or something else. There are many possibilities to do this.
