Hi,
Although the man page says you can sendfile from a
socket,I am unable to do so... I can only send file
from a file, to either a socket or file

Is this a kernel limitation?

Thanks
Lee

Yes, the manpage needs updating, you can only sendfile() from
something that exists in the pagecache (ie not a socket).

Do I need to do something special to enable sendfile
in the kernel?  It works on a 2.2 kernel, but not on a
2.4 kernel (and this is sendfile in general... not
just sockets)

Thanks
Lee

The most recent manpages show this correctly.
