To detach a WebSocket connection and use the \fIcurl_ws_send(3)\fP and \fIcurl_ws_recv(3)\fP functions after the HTTP upgrade procedure, set the \fICURLOPT_CONNECT_ONLY(3)\fP option to 2L. Available bits in the bitmask .IP "CURLWS_RAW_MODE (1)" Deliver "raw" WebSocket traffic to the \fICURLOPT_WRITEFUNCTION(3)\fP callback. In raw mode, libcurl does not handle pings or any other frame for the application. .SH DEFAULT 0 .SH PROTOCOLS WebSocket .SH EXAMPLE .nf CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "ws://example.com/"); /* tell curl we deal with all the WebSocket magic ourselves */ curl_easy_setopt(curl, CURLOPT_WS_OPTIONS, (long)CURLWS_RAW_MODE); ret = curl_easy_perform(curl); curl_easy_cleanup(curl); } .fi .SH AVAILABILITY Added in 7.86.0 .SH RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR curl_ws_recv "(3), " curl_ws_send "(3), "
