NAME

CURLINFO_LASTSOCKET - get the last socket used

SYNOPSIS

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

DESCRIPTION

Deprecated since 7.45.0. Use CURLINFO_ACTIVESOCKET(3) instead. Pass a pointer to a long to receive the last socket used by this curl session. If the socket is no longer valid, -1 is returned. When you finish working with the socket, you must call curl_easy_cleanup() as usual 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). NOTE: this API is deprecated since it is not working on win64 where the SOCKET type is 64 bits large while its 'long' is 32 bits. Use the CURLINFO_ACTIVESOCKET(3) instead, if possible.

PROTOCOLS

All

EXAMPLE

CURL *curl = curl_easy_init(); if(curl) { long sockfd; /* doesn't work on win64! */ 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_LASTSOCKET, &sockfd); if(res != CURLE_OK) { printf("Error: %s\n", curl_easy_strerror(res)); return 1; } }

AVAILABILITY

Added in 7.15.2

RETURN VALUE

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