IOS cocos2dx的套接字

Question

我需要构建一个游戏使用Socket来连接多个设备。 我尝试在cocos2dx上创建套接字时遇到问题。

void AcceptCallBack(
                    CFSocketRef socket,
                    CFSocketCallBackType type,
                    CFDataRef address,
                    const void *data,
                    void *info)
{
    CFReadStreamRef readStream = NULL;
    CFWriteStreamRef writeStream = NULL;
    CFIndex bytes;
    UInt8 buffer[128];
    UInt8 recv_len = 0, send_len = 0;

    /* The native socket, used for various operations */
    CFSocketNativeHandle sock = *(CFSocketNativeHandle *) data;

    /* The punch line we stored in the socket context */
    char *punchline = info;

    /* Create the read and write streams for the socket */
    CFStreamCreatePairWithSocket(kCFAllocatorDefault, sock,
                                 &readStream, &writeStream);

    if (!readStream || !writeStream) {
        close(sock);
        fprintf(stderr, "CFStreamCreatePairWithSocket() failed\n");
        return;
    }

    CFReadStreamOpen(readStream);
    CFWriteStreamOpen(writeStream);

    /* Wait for the client to finish sending the joke; wait for newline */
    memset(buffer, 0, sizeof(buffer));
    while (!strchr((char *) buffer, '\n') && recv_len < sizeof(buffer)) {
        bytes = CFReadStreamRead(readStream, buffer + recv_len,
                                 sizeof(buffer) - recv_len);
        if (bytes < 0) {
            //       fprintf(stderr, "CFReadStreamRead() failed: %d\n", bytes);
            close(sock);
            return;
        }
        //   NSLog(@"Read: %d", bytesRead);
        NSLog(@"buffer: %s", buffer);
        recv_len += bytes;
    }

    /* Send the punchline */
    while (send_len < (strlen(punchline+1))) {
        if (CFWriteStreamCanAcceptBytes(writeStream)) {
            bytes = CFWriteStreamWrite(writeStream,
                                       (unsigned char *) punchline + send_len,
                                       (strlen((punchline)+1) - send_len) );
            if (bytes < 0) {
                fprintf(stderr, "CFWriteStreamWrite() failed\n");
                close(sock);
                return;
            }
            send_len += bytes;
        }
        close(sock);
        CFReadStreamClose(readStream);
        CFWriteStreamClose(writeStream);
        return;
    }
}

我在Ios应用程序上运行时一切正常（创建新项目时Xcode的默认设置）

但是当我将该源代码复制到由Cocos2dx创建的项目时。 我在这一行得到了一个错误：

char *punchline = info;

错误讯息：

Can not initialize a variable of type 'char *' with an Ivalue of type 'void *'

我不知道应该更改哪个设置来运行它。 感谢。
