Procedure signature

    • ... -- at least 2 times;
  • output: a value of type boolean;

Description

§

(char-ci=? char_1 char_2 char_3 ...)
(char-ci<? char_1 char_2 char_3 ...)
(char-ci>? char_1 char_2 char_3 ...)
(char-ci<=? char_1 char_2 char_3 ...)
(char-ci>=? char_1 char_2 char_3 ...)

These procedures are similar to char=? et cetera, but they treat upper case and lower case letters as the same. For example, (char-ci=? #\A #\a) returns #t.

Specifically, these procedures behave as if char-foldcase were applied to their arguments before they were compared.
