WCTYPE(3)						     Linux Programmer's Manual							 WCTYPE(3)

NAME
wctype - wide-character classification SYNOPSIS
#include <wctype.h> wctype_t wctype(const char *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 charac- ters. 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(3) 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. "alnum" - realizes the isalnum(3) classification function "alpha" - realizes the isalpha(3) classification function "blank" - realizes the isblank(3) classification function "cntrl" - realizes the iscntrl(3) classification function "digit" - realizes the isdigit(3) classification function "graph" - realizes the isgraph(3) classification function "lower" - realizes the islower(3) classification function "print" - realizes the isprint(3) classification function "punct" - realizes the ispunct(3) classification function "space" - realizes the isspace(3) classification function "upper" - realizes the isupper(3) classification function "xdigit" - realizes the isxdigit(3) classification function RETURN VALUE
The wctype() function returns a property descriptor if the name is valid. Otherwise, it returns (wctype_t) 0. ATTRIBUTES
