detach-ssl

Function
Summary

Detaches the SSL from a socket stream.

Signature

detach-ssl socket-stream &key retry-count retry-timeout

Arguments

socket-stream

A socket-stream.

retry-count

A non-negative integer.

retry-timeout

Description

The function detach-ssl detaches the SSL from the socket-stream socket-stream . If socket-stream is not attached to an SSL, detach-ssl just returns immediately. Otherwise, it detaches the SSL from socket-stream , tries to shut down the SSL cleanly, and then frees the objects that were allocated by attach-ssl.

retry-count specifies how many additional times to call SSL_shutdown after the second to attempt to get a successful shutdown. The default value of retry-count is 5.

retry-timeout specifies the time in seconds to wait between each of the calls to SSL_shutdown . If it fails to get a successful shudown after these attempts, detach-ssl signals an error. The default value of retry-timeout is 0.1.

Note that the shutdown calls happen after the SSL has been detached from socket-stream as far as LispWorks is concerned, so if an error occurs at this point and is aborted, socket-stream can be used in attach-ssl again (assuming that the peer can cope with this situation).

If retry-count is nil , detach-ssl does not try to get a successful shutdown call. This value is used when the stream is closed, but should not be used normally.
