This is how the RFC calls the protocol. Also rename the file in docs/ to WEBSOCKET.md in uppercase to match how we have done it for many other protocol docs in similar fashion. Add the WebSocket docs to the tarball. Closes #9496

|
.SH NAME
|
|
curl_ws_recv - receive WebSocket data
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/easy.h>
|
|
|
|
CURLcode curl_ws_recv(CURL *curl, void *buffer, size_t buflen,
|
|
size_t *recv, unsigned int *recvflags);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
This function call is EXPERIMENTAL.
|
|
|
|
Retrives as much as possible of a received WebSocket data fragment into the
|
|
\fBbuffer\fP, but not more than \fBbuflen\fP bytes. The provide
|
|
\fIrecvflags\fP argument gets bits set to help characterize the fragment.
|
|
.SH RECVFLAGS
|
|
.IP CURLWS_TEXT
|
|
The buffer contains text data. Note that this makes a difference to WebSocket
|
|
but libcurl itself will not make any verification of the content or
|
|
precautions that you actually receive valid UTF-8 content.
|
|
.IP CURLWS_BINARY
|
|
This is binary data.
|
|
.IP CURLWS_FINAL
|
|
This is the final fragment of the message, if this is not set, it implies that
|
|
there will be another fragment coming as part of the same message.
|
|
.IP CURLWS_CLOSE
|
|
This transfer is now closed.
|
|
.IP CURLWS_PING
|
|
This as an incoming ping message, that expects a pong response.
