wctype: definovat třídu znaků

Originální popis anglicky: wctype - define character class

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <wctype.h>
 
 
wctype_t wctype(const char * property);
 

POPIS / INSTRUKCE

The wctype() function is defined for valid character class names as defined in the current locale. The property argument is a string identifying a generic character class for which codeset-specific type information is required. The following character class names shall be defined in all locales:
alnum alpha blank cntrl digit graph lower print punct space upper xdigit
Additional character class names defined in the locale definition file (category LC_CTYPE ) can also be specified.
The function shall return a value of type wctype_t, which can be used as the second argument to subsequent calls of iswctype(). The wctype() function shall determine values of wctype_t according to the rules of the coded character set defined by character type information in the program's locale (category LC_CTYPE ). The values returned by wctype() shall be valid until a call to setlocale() that modifies the category LC_CTYPE .

NÁVRATOVÁ HODNOTA

The wctype() function shall return 0 if the given character class name is not valid for the current locale (category LC_CTYPE ); otherwise, it shall return an object of type wctype_t that can be used in calls to iswctype().
