CURLINFO_ACTIVESOCKET(3)   curl_easy_getinfo options  CURLINFO_ACTIVESOCKET(3)

NAME

CURLINFO_ACTIVESOCKET - get the active socket

SYNOPSIS

#include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_ACTIVESOCKET, curl_socket_t *socket);

DESCRIPTION

Pass a pointer to a curl_socket_t to receive the active socket used by this curl session. If the socket is no longer valid, CURL_SOCKET_BAD is returned. When you finish working with the socket, you must call curl_easy_cleanup(3) as usual on the easy handle and let libcurl close the socket and cleanup other resources associated with the handle. This is typically used in combination with CURLOPT_CONNECT_ONLY(3). This option was added as a replacement for CURLINFO_LASTSOCKET(3) since that one isn't working on all platforms.

PROTOCOLS

All

EXAMPLE

CURL *curl = curl_easy_init(); if(curl) { curl_socket_t sockfd; curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); /* Do not do the transfer - only connect to host */ curl_easy_setopt(curl, CURLOPT_CONNECT_ONLY, 1L); res = curl_easy_perform(curl); /* Extract the socket from the curl handle */ res = curl_easy_getinfo(curl, CURLINFO_ACTIVESOCKET, &sockfd); if(res != CURLE_OK) { printf("Error: %s\n", curl_easy_strerror(res)); return 1; } }

AVAILABILITY

Added in 7.45.0

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
