作为工作示例,我们可以处理以下代码:

    #include <sys/socket.h>

    #define size_t   SOCKET

    int receive_socket_data(SOCKET sock,//socket representing remote connection
                            unsigned long& version_number,//validPtr->version #
                            unsigned long& message_size,//validPtr->sizeof packet
                            char*& buf // where to copy data from packet
                           )
    {
       int nlen = 0;
       buf = NULL;

       // Receive version_number from the packet
       nlen = recv(sock, (char*) &version_number, sizeof(version_number), 0);
       if (nlen == 0 || nlen == -1) return ERROR_RECEIVING;
       version_number = ntohl(version_number);

       // Receive message_size from the entire packet 
       // (ulong + ulong + sizeof data)
       nlen = …
