Retrieves as much as possible of a received WebSocket data fragment into the \fBbuffer\fP, but not more than \fBbuflen\fP bytes. \fIrecv\fP is set to the number of bytes actually stored. If there is more fragment data to deliver than what fits in the provided \fIbuffer\fP, libcurl returns a full buffer and the application needs to call this function again to continue draining the buffer. The \fImeta\fP pointer gets set to point to a \fIstruct curl_ws_frame\fP that contains information about the received data. See the \fIcurl_ws_meta(3)\fP for details on that struct. .SH EXAMPLE .nf .fi .SH AVAILABILITY Added in 7.86.0. .SH RETURN VALUE .SH "SEE ALSO" .BR curl_easy_setopt "(3), " curl_easy_perform "(3), " .BR curl_easy_getinfo "(3), " .BR curl_ws_send "(3) "
