Hello, I'm done with my networking-stack project (transport protocol) and I'm writing the docs now (borrrring). I registered a function 'xxx_sendmsg' in the 'struct proto' to be called for 'sendmsg' operation on the socket and it workes fine. Since this is not my part, I don't really know what is the exact chain of calls when user calls send(). I need to know what happens from send() called by user to 'xxx_sendmsg'. Also, I need to know how this chain changes when the user calls 'write()' instead of 'send()'. btw. this is a connection-oriented protocol.
