.TH curl_ws_recv 3 "12 Jun 2022" "libcurl 7.85.0" "libcurl Manual"
.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 *flags);
.fi
.SH DESCRIPTION
This function call is EXPERIMENTAL.

Retrieves as much as possible of a received WebSocket data fragment into the
\fBbuffer\fP, but not more than \fBbuflen\fP bytes. The provide
\fIflags\fP argument gets bits set to help characterize the fragment.
.SH FLAGS
.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_CONT
This is not the final fragment of the message, 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.
.SH EXAMPLE

.SH AVAILABILITY
