install-single-channel-character-strategy

Arguments: stream format access

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

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 single-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; the external-format is looked up (possibly causing autoloading, compilation of the templates, and/or loading of pre-built external-formats).

Normally, access should be specified as nil. If specified as either the symbol excl::buffer or the smbol excl::mapped, installation of special buffer-oriented or mapped templates will be done. Note however, that these options are not exported and thus not documented, and should not be counted on remaining unchanged in future versions of Allegro CL.

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.
