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.
