I don't see anywhere on that page where is says that a timeout of zero makes it non-blocking. What it says is "If the timeout is set to zero (the default) then the operation will never timeout." That does not mean the operation will always immediately return (non-blocking). That means the operation will block forever (there will be no timeout) until it completes completes. -- Grant _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
