CFSocket: No accept callback? Here's the problem:

gistfile1.m

// Doesn't work:
    readsock = CFSocketCreate(kCFAllocatorDefault, PF_INET, SOCK_STREAM,
                              IPPROTO_TCP, kCFSocketReadCallBack |
                              kCFSocketAcceptCallBack | kCFSocketDataCallBack |
                              kCFSocketConnectCallBack | kCFSocketWriteCallBack,
                              (CFSocketCallBack)&readSockCallBack, info);

// Works:
    readsock = CFSocketCreate(kCFAllocatorDefault, PF_INET, SOCK_STREAM,
                              IPPROTO_TCP, kCFSocketAcceptCallBack,
                              (CFSocketCallBack)&readSockCallBack, info);
