It says that "Returns the number of bytes sent, or a negative error code.",
but it may still not be clear. What do you propose?

I'm trying not to tight gnutls to berkeley style sockets, or even TCP/IP.

gnutls_bye() and any other gnutls function (except of gnutls_read()/write()),
do not call any external function such as shutdown. 
Thus in your case if the return value is zero you may continue using the connection.

Documentation in gnutls is in latex format. This can be
converted to several other formats. (and possibly info format but
I'm not sure)
