POPIS / INSTRUKCE

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.

  "alnum" - realizes the  isalnum classification function
  "alpha" - realizes the  isalpha classification function
  "blank" - realizes the  isblank classification function
  "cntrl" - realizes the  iscntrl classification function
  "digit" - realizes the  isdigit classification function
  "graph" - realizes the  isgraph classification function
  "lower" - realizes the  islower classification function
  "print" - realizes the  isprint classification function
  "punct" - realizes the  ispunct classification function
  "space" - realizes the  isspace classification function
  "upper" - realizes the  isupper classification function
  "xdigit" - realizes the  isxdigit classification function

NÁVRATOVÁ HODNOTA

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

NOTES

The behaviour of wctype depends on the LC_CTYPE category of the current locale.
