How to apply Linger option with winsock2
To apply the Linger option using Winsock2 in C++, you can use the setsockopt
function with the SO_LINGER
option. Here's an example:
cpp#include <winsock2.h>
// Create a socket
SOCKET socket = socket(AF_INET, SOCK_STREAM, 0);
// Set the Linger option
LINGER lingerOption;
lingerOption.l_onoff = 1; // Enable Linger
lingerOption.l_linger = 0; // Set the Linger time in seconds (0 means immediate close)
int result = setsockopt(socket, SOL_SOCKET, SO_LINGER, (const char*)&lingerOption, sizeof(lingerOption));
if (result == SOCKET_ERROR) {
// Error handling
}
// Close the socket
closesocket(socket);
In this example, we create a socket using the socket
function. Then, we define a LINGER
structure and set the l_onoff
field to 1
to enable the Linger option. We set the l_linger
field to 0
to specify an immediate close (the socket will be closed immediately without waiting for pending data to be sent or received).
Next, we use the setsockopt
function to apply the Linger option to the socket. We pass the SO_LINGER
option, the socket handle, the LINGER
structure, and the size of the structure.
Finally, we close the socket using the closesocket
function.
Please note that error handling and additional code for creating and binding the socket are not shown in this example. Make sure to include the necessary code for creating and initializing the socket before setting the Linger option.
