26 * This is a Standard C++ Library file. You should @c \#include this file
27 * in your programs, rather than any of the @a *.h implementation files.
28 *
29 * This is the C++ version of the Standard C Library header @c wctype.h,
30 * and its contents are (mostly) the same as that header, but are all
31 * contained in the namespace @c std (except for names which are defined
32 * as macros in C).
