9.2.3 Making Your Own Wires

You can create wires manually in addition to the remote package’s interface creating them for you. To create a wire, you need a Unix file descriptor. If you are unfamiliar with Unix file descriptors, see section 2 of the Unix manual pages.

Function: wire:make-wire descriptor ¶

The function make-wire creates a new wire when supplied with the file descriptor to use for the underlying I/O operations.

Function: wire:wire-p object ¶

This function returns t if object is indeed a wire, nil otherwise.

Function: wire:wire-fd wire ¶

This function returns the file descriptor used by the wire.
