Re: UDP packets greater than 510 bytes clipped

I'm using the socket, bind and sendto calls to establish and send UDP data, and NSFileHandle's readInBackgroundAndNotify to read. Would I be right in discovering readToEndOfFileInBackgroundAndNotify does not apply to UDP?



NSFileHandle is not really designed for datagram-oriented protocols.  I would suggest using CFSocket instead, if you wish to receive notifications of data on your run loop.  

Something like

    CFSocketRef s = CFSocketCreateWithNative(NULL, sock, kCFSocketDataCallBack, dataArrived, NULL);
    CFRunLoopSourceRef source = CFSocketCreateRunLoopSource(NULL, s, 0);
    CFRunLoopAddSource(CFRunLoopGetCurrent(), source, kCFRunLoopDefaultMode);

where sock is your UDP socket and

void dataArrived(CFSocketRef s, CFSocketCallBackType type, CFDataRef address, const void *data, void *info) {
    // this is your callback, data is a CFDataRef containing your data
}
