How does libpcap get a package from the driver?

Question

Can someone point me to a good starting place to find out how libpcap gets its packages from the network driver? I intend to replace the receive function with a quick implementation.

Answer 1

"Receive Function":

• standard function for receiving drivers, not different from that used to receive packets and send them to a regular network stack;
• part of the "packet socket" of the regular network stack.
