NAME

       CURLOPT_WS_OPTIONS - WebSocket behavior options

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WS_OPTIONS, long bitmask);

DESCRIPTION

       Pass a long with a bitmask to tell libcurl about specific WebSocket behaviors.

       To detach a WebSocket connection and use the curl_ws_send(3) and curl_ws_recv(3) functions
       after the HTTP upgrade procedure, set the CURLOPT_CONNECT_ONLY(3) option to 2L.

       Available bits in the bitmask

       CURLWS_RAW_MODE (1)
              Deliver "raw" WebSocket traffic to the CURLOPT_WRITEFUNCTION(3) callback.

              In raw mode, libcurl does not handle pings or any other frame for the application.

DEFAULT

       0

           curl_easy_setopt(curl, CURLOPT_URL, "ws://example.com/");
           /* tell curl we deal with all the WebSocket magic ourselves */
