|
|
|
|
|
.IP CURLWS_TEXT
|
|
|
|
|
|
The buffer contains text data. Note that this makes a difference to WebSockets
|
|
|
|
|
|
but libcurl itself will not make any verification of the content or
|
|
|
|
|
|
precautions that you actually send valid UTF-8 content.

|
|
|
|
|
.IP CURLWS_BINARY

This is binary data.

|
|
No-op if there’s no compression anyway.
|
|
|
|
|
|
.IP CURLWS_CONT
|
|
|
|
|
|
This is not the final fragment of the message, which implies that there will
|
|
|
|
|
|
be another fragment coming as part of the same message where this bit is not
|
|
|
|
|
|
set.
|
|
|
