sal_socket()和sal_accept()都调用了socket_new()，不是生成和占用两个块了吗？
int sal_socket(int domain, int type, int protocol){ int retval; int socket, proto_socket; struct sal_socket *sock; struct sal_proto_family *pf; /* allocate a new socket and registered socket options */ socket = socket_new(); //?????????????????????????????????????? if (socket < 0) { return -1; } ......}int sal_accept(int socket, struct sockaddr *addr, socklen_t *addrlen){ int new_socket; struct sal_socket *sock; struct sal_proto_family *pf; /* get the socket object by socket descriptor */ SAL_SOCKET_OBJ_GET(sock, socket); /* check the network interface socket operations */ SAL_NETDEV_SOCKETOPS_VALID(sock->netdev, pf, accept); new_socket = pf->skt_ops->accept((int) sock->user_data, addr, addrlen); if (new_socket != -1) { int retval; int new_sal_socket; struct sal_socket *new_sock; /* allocate a new socket structure and registered socket options */ new_sal_socket = socket_new(); //??????????????????????????? if (new_sal_socket < 0) { pf->skt_ops->closesocket(new_socket); return -1; } ......}
