Socket options

Hi everyone,

Question for gurus:

Is there a way for us to determine the options used by a socket?

I basically want to know if SO_KEEPALIVE is enabled on a socket to know if the tcp_keepalive_abort_interval parameter will be used by that connection.

Was I clear enough? Smilie

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 If the socket is no longer valid, CURL_SOCKET_BAD is returned.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
TODO AVAILABILITY
Added in 7.45.0 RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. SEE ALSO
