The GnuTLS library is detected automatically at compile time. You
should see that it’s enabled in the
configure output. If not,
follow the standard procedure for finding out why a system library is
not picked up by the Emacs compilation. On the W32 (Windows)
platform, installing the DLLs with a recent build should be enough.
(the two are equivalent, the first one being an alias to the second).
You should not have to use the gnutls.el functions directly.
But you can test them with
This function creates a buffer connected to a specific host and
service (port number or service name). The parameters and their
syntax are the same as those given to
(see Network Connections in The Emacs Lisp Reference
Manual). The connection process is called name (made unique if
necessary). This function returns the connection process.
;; open a HTTPS connection (open-gnutls-stream "tls" "tls-buffer" "yourserver.com" "https") ;; open a IMAPS connection (open-gnutls-stream "tls" "tls-buffer" "imap.gmail.com" "imaps")
gnutls-negotiate is not generally useful and it
may change as needed, so please see gnutls.el for the details.
Please see gnutls.el for the spec details and for usage, but do not rely on this function’s interface if possible.
