|
|
|
||
|
|
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.

|
