CURLOPT_CLOSESOCKETFUNCTION(3)				     curl_easy_setopt options				    CURLOPT_CLOSESOCKETFUNCTION(3)

NAME

       CURLOPT_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 prototype 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_OPENSOCKETFUNCTION(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.
