Description of the send and Recv functions of socketapi
Today, we will further explain the socketapi series of functions. Other listen, connect, and accept functions have been mentioned. This article focuses on sending and Recv functions.
Send
1. send recv is the file descriptor for the set interface.Read write requires a file descriptor.
Read and write can also process socket fdThe two are consistent on BSD4.4 and will eventually be tuned to a unified kernel processing function, but the
What is the difference between read () and recv ()?From Andrew Gierth (andrew@erlenstar.demon.co.uk):Read () is equivalent to recv () with a flags parameter of 0. Other values for the flags parameter change the behaviour of recv (). Similarly, write
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
Both Recv and recvfrom are used to accept data from the network. Let's take a look at their prototype:
Int Recv (Socket{Function onclick (){Function onclick (){Showtip (this)}}} "> S,Char far*{Function onclick (){Function onclick (){Showtip (this)}
100 solve the problem of madcodehook hook send and Recv. Delphi/Windows SDK/API

Currently, the hook window can be normally called out, but the packets cannot be recorded
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
First, define a concept: Each TCP socket has a sending buffer and a receiving buffer in the kernel, the full duplex mode of TCP and the Sliding Window of TCP depend on the two independent buffers and the filling status of the buffer. The receiving
Windows is connected to linux, and the command line terminal can be connected. Why cannot the file transfer terminal be connected? -- Linux general technology-Linux technology and application information. For details, refer to the following section.
