ConceptsA. BlockingBlocking call means that the current thread will be suspended before the call result is returned. The function is returned only after the result is obtained.Some people may equate

Blocking Mode Windows Socket performs I/O operations in both blocking and non-blocking modes. In blocking mode, the operation function to be executed waits until the I/O operation is completed without returning immediately. The thread where the function is located will be blocked here. On the contrary, in non-

I. OverviewWhat is the difference between synchronous (synchronous) IO and asynchronous (asynchronous) Io, what is blocking (blocking) IO and non-blocking (non-blocking) IO respectively? The problem is that different people may give different answers, such as wikis, that asynchronous IO and non-

Old Zhang loves drinking tea, without talking nonsense, and boiling water. Appearance character: Lao Zhang, two kettle (ordinary kettle for short; ring kettle for short ). 1. Old Zhang put the kettle on the fire and waited for the water to open. (Synchronous blocking) Lao Zhang thinks he is a bit silly. 2. Old Zhang put the kettle on the fire, went to the living room to watch TV, and went to the kitchen from time to see if the water was open. (Non-

To put it more simply: Obstruction is not to do not come back, has been waiting until the matter is completed before returning;If you do it first, I'll see if there's anything else. No, as soon as I found out something was stuck, I immediately reported to the leader. Let's take the most commonly used send and recv two functions ...For example, you call the Send function to send a certain byte, in the system sent to do the work is actually just the data transfer (COPY) to the TCP/IP protocol st

If you want to have a kung pao chicken rice: Synchronous congestion: you order food at the restaurant, and then wait there, and you have to shout: Okay! Synchronous non-blocking: after ordering at the restaurant, you can walk the dog. But after a while, I went back to the restaurant and shouted: Okay! Asynchronous blocking: when walking the dog, you receive a call from the restaurant saying that the meal is

synchronous asynchronous blocking non-blocking Today and the small partners to discuss this issue, the online statement there are many kinds of, I follow my own ideas to summarize one side.A sentence summarizes the difference:Synchronous Async is concerned with your behavior when an event occurs.The state of the wait event that is blocking the non-

1. What do the returned values of Recv in blocking mode and non-blocking mode mean? Is there a difference? (As far as I know at present, there is no distinction between blocking and non-blocking Recv return values, all of which are 2. What do the return values of write in blocki
