C++ (Cpp) CB_INIT Examples

Example #1

File: v_api.c Project: pqhwan/TCP

//malloc and initialize sending and receiving window
void init_windows(socket_t *so) {

	so->sendw = malloc(sizeof(sendw_t));
	so->recvw = malloc(sizeof(recvw_t));
	CB_INIT(&so->sendw->buf, WINSIZE);

	CB_INIT(&so->recvw->buf, WINSIZE); 

	pthread_mutexattr_t mutexattr;
	pthread_mutexattr_init(&mutexattr);
	pthread_mutex_init(&so->sendw->lock, &mutexattr);

	so->sendw->retrans_q_head = NULL; //retransmissionqueue
	so->sendw->ackhistory = NULL; //ack history table
	so->sendw->hack = so->myseq+1;  //highest ack TODO wrap
	so->sendw->rto = 0.00350;
	so->sendw->srtt = 0.00350;

	so->recvw->oor_q_head = NULL; //out of order packet list
	so->recvw->oor_q_size = 0;
