  1. getsockopt and setsockopt Functions These two functions are only used for sockets: # Include int getsockopt (int sockfd, int level, int optname, void * optval, socklen_t * optlen); int setsockopt (int sockfd, int level, int optname, const void

Article title: Linux network programming-8. socket options. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open

Set SO_RECVBUF and SO_SENDBUF socket options, sorecvbuf Control socket behavior (such as modifying the buffer size ). Int getsockopt (int sockfd, int level, int optname, void * optval, socklen_t * optlen ); Int setsockopt (int sockfd, int level, int

Socket options are typically set through the following functions: GetSockOpt and SETSOCKOPT functions; fcntl functions; IOCTL functions #include /* See NOTES */ #include int getsockopt ( int sockfd int

Linux Network Programming socket options so_linger, so_reuseaddr In Linux network programming, there are many socket options. Several of the most important options are: so_linger (only applicable to TCP and sctp), so_reuseaddr.   So_linger By

In some cases, we need to further control the socket behavior and attributes, such as modifying the buffer size and viewing the socket status. Therefore, we need to set/obtain the socket options. 1. Obtain socket optionsint getsockopt(SOCKET s,int

Linux program design-socket options (Chapter 1), linux Program DesignNow we can improve the customer program so that it can be connected to any host with a name. This time, instead of connecting to the sample server, it is connected to a standard

The socket mechanism provides two socket option interfaces to control the behavior of sockets. An interface is used to set options, and another interface is used to allow us to request the status of the option. We can get and set three kinds of

/* Set the socket option to periodically detect the connectivity heartbeat packet and Xinbo. It is mainly used for persistent connections. * Parameter: socket, 1 or 0 enabled, first interval, two intervals, number of disconnections */void

Erlang R17 introduces the new socket option {active, N}. Together with {active, once}, it provides traffic control for the application layer. Why does the option {active, once} effectively suppress a large number of socket messages? We know that

Now you can improve the client program so that it can connect to any host that has a name, this time not connecting to the sample server, but connecting to a standard service, so that you can demonstrate the port number extraction operationThe.Most

From http://blog.csdn.net/feiyinzilgd/article/details/5894300In Linux network programming, there are many options for sockets. Several of the more important options are: So_linger (only for TCP,SCTP), so_reuseaddr. So_linger By default,

now it is possible to improve the client program so that it can connect to any host with no name, this time instead of connecting to the Demo sample server, but connecting to a standard service so that it can demonstrate the port number extraction

Sometimes we need to control the behavior of sockets (such as changing the size of the buffer), and we're going to learn the socket options. int getsockopt (int sockfd,int level,int optname,void *optval,socklen_t *optlen) int setsockopt (int

1.Closesocket (usually does not close immediately and goes through the time_wait process) and wants to continue to reuse the socket:Bool breuseaddr = true;Setsockopt(S, sol_socket, so_reuseaddr, (const char *) & breuseaddr, sizeof (bool )); 2.If you

A tcp disconnection exception occurs when a sudden power failure or network cable disconnection occurs. If no data transmission or communication is processed by both parties, the connection is disconnected. In general, in order to prevent socket
