switch-ef-to-runtime

Arguments: external-format

external-format should be an external-format.

Switches an external-format to runtime mode. The def-ef-switch-to-runtime macro is used to name a function (or function object) that when funcalled clears structures used by the macros that are not needed when the external-format is in runtime mode. switch-ef-to-runtime funcalls this function and also clears the char-to-octets/octets-to-char convertor macros.

Generally, users will not call switch-ef-to-runtime. When an external-format is autoloaded, an attempt is made to autoload the pre-filled external-format code templates. These pre-filled templates are stored in separate fasl files, usually with names that begin with 'efft-'. If the pre-filled templates are successfully loaded, then Allegro CL automatically switches the just-loaded external-format to runtime mode using switch-ef-to-runtime.
