install-dual-channel-character-strategy

Arguments: stream format

In earlier releases, the symbol naming this function was dual-channel-install-ef-methods. That symbol is no longer exported. Use this new name instead.

You must load the :iodefs module to use this function. Do that by evaluating (require :iodefs). (It is not an error to evaluate that form if the module is already loaded.)

This function is called for its side-effects. Its return value is unspecified. This function installs character handlers into the stream that are appropriate for dual-channel streams, and also sets the external-format state slots to nil. The selection of which external-format handlers are used is based on the format argument; the external-format is looked up (possibly causing autoloading, compilation of the templates, and/or loading of pre-built external-formats).

You must load the :iodefs module to use this function. Do that by evaluating (require :iodefs). (It is not an error to evaluate that form if the module is already loaded.) This function is intended for implementing device-level functionality and should not be used except for that purpose. See Simple-stream Description in streams.htm for a description of the device-level.

See streams.htm for information on the simple-streams implementation in Allegro CL.
