## ef-width

Arguments: external-format

This function returns the number of octets it takes to build a character in the argument external-format. It may have an integer value or the value `character`. The width slot of an external format is used to optimize listen techniques in a stream; by default listen requires at least ef-width octets to be available before returning true. Normally this means having to go through the process of building a character, but in simple formats, like latin1, availability of a single octet can allow a true return from listen.

See def-external-format. See iacl.htm for more information on international character support in Allegro CL.
