| 2421 | If you're setting up an asynchronous TLS connection, you have to also | ||
| 2422 | provide the @code{:tls-parameters} parameter (see below). | ||
| 2423 | |||
| 2424 | Depending on the capabilities of Emacs, how asynchronous | ||
| 2425 | @code{:nowait} is may vary. The three elements that may (or may not) | ||
| 2426 | be done asynchronously are domain name resolution, socket setup, and | ||
| 2427 | (for TLS connections) TLS negotiation. | ||
| 2428 | |||
| 2429 | Many functions that interact with process objects, (for instance, | ||
| 2430 | @code{process-datagram-address}) rely on them at least having a socket | ||
| 2431 | before they can return a useful value. These functions will block | ||
| 2432 | until the socket has achieved the desired status. The recommended way | ||
| 2433 | of interacting with asynchronous sockets is to place a sentinel on the | ||
| 2434 | process, and not try to interact with it before it has changed status | ||
| 2435 | to @samp{"run"}. That way, none of these functions will block. | ||
| 2436 | |||
| 2437 | @item :tls-parameters | ||
| 2438 | When opening a TLS connection, this should be where the first element | ||
| 2439 | is the TLS type (which should either be @code{gnutls-x509pki} or | ||
| 2440 | @code{gnutls-anon}, and the remaining elements should form a keyword | ||
| 2441 | list acceptable for @code{gnutls-boot}. (This keyword list can be | ||
| 2442 | optained from the @code{gnutls-boot-parameters} function.) The TLS | ||
| 2443 | connection will then be negotiated after completing the connection to | ||
| 2444 | the host. | ||
