.TH CURLINFO_ACTIVESOCKET 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
|
|
.SH NAME
|
|
CURLINFO_ACTIVESOCKET \- get the active socket
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_ACTIVESOCKET,
|
|
curl_socket_t *socket);
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a curl_socket_t to receive the most recently active socket
|
|
used for the transfer connection by this curl session. If the socket is no
|
|
longer valid, \fICURL_SOCKET_BAD\fP is returned. When you are finished working
|
|
with the socket, you must call \fIcurl_easy_cleanup(3)\fP as usual on the easy
|
|
handle and let libcurl close the socket and cleanup other resources associated
|
|
with the handle. This option returns the active socket only after the transfer
|
|
is complete, and is typically used in combination with
|
|
\fICURLOPT_CONNECT_ONLY(3)\fP, which skips the transfer phase.
|
|
|
|
\fICURLINFO_ACTIVESOCKET(3)\fP was added as a replacement for
|
|
\fICURLINFO_LASTSOCKET(3)\fP since that one isn't working on all platforms.
