How do cvs client server communicate

[PJP]

   Hello all,
I am reading the cvs source, and have got some questions, If I'm not
wrong,
open_connection_to_server(): this function opens up a connection, and
provides * to_server_p *, and * from_server_p * buffers  to  cvs client
to communicate with the server using * send_to_server() * and *
read_from_server() * functions.

now, which function on the server(.c) side listens for requests from
client side. and also what is start_server used for.

 could you pls explain me about this ?
