.TH CURLOPT_CLOSESOCKETFUNCTION 3 "16 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_CLOSESOCKETFUNCTION \- callback to socket close replacement function
.SH SYNOPSIS
#include <curl/curl.h>

int closesocket_callback(void *clientp, curl_socket_t item);

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CLOSESOCKETFUNCTION, closesocket_callback);
.SH 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 \fIclose(3)\fP or
\fIclosesocket(3)\fP call when sockets are closed (not for any other file
descriptors). This is pretty much the reverse to the
\fICURLOPT_OPENSOCKETFUNCTION(3)\fP option. Return 0 to signal success and 1
if there was an error.

The \fIclientp\fP pointer is set with
\fICURLOPT_CLOSESOCKETDATA(3)\fP. \fIitem\fP is the socket libcurl wants to be
closed.
.SH DEFAULT
By default libcurl uses the standard socket close function.
