@ -50,9 +50,17 @@ This function requires an easy handle as input argument for libcurl to know
what transfer the question is about, but as there is no such pointer provided
to the callback by libcurl itself, applications that want to use
\fIcurl_ws_meta(3)\fP need to pass it on to the callback on its own.
.SH "struct fields"
.IP age
This field specify the age of this struct. It is always zero for now.
.IP recvflags
This is a bitmask with the exact same meaning as the \fBrecvflags\fP
documented for \fIcurl_ws_recv(3)\fP.
