how to create a interrupt service function in c for real time linux operating system?

Question

Scenario : Client is sending a data and the server is receving the data from client via ethernet layer (udp). When the server receives a data from the client on the ip layer (kernel). It interrupts the kernel and kernel as to execute the data by the client, so I want to create a interrupt service function to catch the interrupt from the network service card.

could someone help me how to go about it ?

Like Alnitak above, I question that you really want to bypass the networking services of your operating system(s), which are real-time after all. So, I suggest you follow Basile Starynkevitch's advice and use poll , select or even just recv from a task with adequate scheduling policy and priority.
