# NAME
CURLOPT_WS_OPTIONS - WebSocket behavior options
# SYNOPSIS
~~~c
#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

# EXAMPLE
~~~c
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
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);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
