When you debug your project code, you find a strange problem that is recorded as follows: In non-blocking mode, connect initiates a chain and returns-1 (this is a normal phenomenon in non-blocking mode). Then listen to the write event for the socket,

The system provides a socket buffer size of 8K, which you can set to 64K, especially when streaming live video. When the socket sends data to send data to the socket buffer, then accept the function and then fetch the data from the buffer, if the
