NAME

wctype - wide character classification

SYNOPSIS

#include name);

DESCRIPTION

The wctype_t type represents a property which a wide character may or may not have. In other words, it represents a class of wide characters. This type's nature is implementation dependent, but the special value (wctype_t)0 denotes an invalid property. Nonzero wctype_t values can be passed to the iswctype function to actually test whether a given wide character has the property.

The wctype function returns a property, given by its name. The set of valid names depends on the LC_CTYPE category of the current locale, but the following names are valid in all locales.

isalnum__ classification function

isalpha classification function isblank classification function iscntrl classification function isdigit classification function isgraph classification function islower classification function isprint classification function ispunct classification function isspace classification function isupper classification function isxdigit classification function

RETURN VALUE

The wctype function returns a property descriptor if the name is valid. Otherwise it returns (wctype_t)0.
