CURLOPT_CLOSESOCKETFUNCTIONcurl_easy_setopt optiCURLOPT_CLOSESOCKETFUNCTION(3)NAMECURLOPT_CLOSESOCKETFUNCTION - callback to socket close replacement
function
SYNOPSIS
#include <curl/curl.h>
int closesocket_callback(void *clientp, curl_socket_t item);
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CLOSESOCKETFUNCTION,
closesocket_callback);
DESCRIPTION
Pass a pointer to your callback function, which should match the proto‐
type shown above.
This callback function gets called by libcurl instead of the close(3)
or closesocket(3) call when sockets are closed (not for any other file
descriptors). This is pretty much the reverse to the CURLOPT_OPENSOCK‐
ETFUNCTION(3) option. Return 0 to signal success and 1 if there was an
error.
The clientp pointer is set with CURLOPT_CLOSESOCKETDATA(3). item is the
socket libcurl wants to be closed.
DEFAULT
By default libcurl uses the standard socket close function.
