.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.
|
|
|
