recv timeout

Int send (socket S, const char far * Buf, int Len, int flags ); Both the client and server applications use the send function to send data to the other end of the TCP connection. The client program generally uses the send function to send requests

Connect Timeout: Currently, the common method for setting SOCKET connect timeout on each platform is to use select (). The specific method is as follows: 1. Establish socket; 2. Set the socket to non-blocking mode; 3. Call connect (); 4. Use select (

Setsockopt () usage (parameter description) recv, send timeout processing, setsockoptrecv Source: recv send blocking and non-blocking Int setsockopt (SOCKET s,Int level,Int optname,Const char * optval,Int optlen); S (socket): point to an open set

VC ++ uses setsockopt () to control the timeout between recv () and send (). setsockoptrecv In the send () and recv () processes, sometimes due to network conditions and other reasons, sending and receiving cannot be performed as expected, and

recv function int recv (SOCKET s, char FAR *buf, int len, int flags); Both the client and the server application receive data from the other end of the TCP connection using the Recv function. The first parameter of the function specifies the receive-

Recv is one of the most commonly used functions in socket programming. Sometimes different values are returned for the blocked Recv, and corresponding error codes for the error values correspond to different States, the following is a brief summary

SsUsed to display the socket information in the active state. The SS command can be used to get socket statistics, which can display and netstat similar content. But the advantage of the SS is that it can show more and more detailed information

Send blockingThe socket recv send interface is blocked, which causes the server side not to respond to any requests from the client, so the socket is set to a non-blocking state in general.However, some scenarios, such as ssl_accept, need to use a

A strange phenomenon was found in the development of a program based on rtmp chat.Under Windows, when we perform closesocket operations, the blocked recv immediately returns-1.And under Linux, when we do the close operation, the blocked Recv will
