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



 

NAME


       wctype - wide-character classification

 

SYNOPSIS


       #include 

       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.  Non-zero wctype_t val-
       ues  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.

 

CONFORMING TO


       C99.

 

NOTES


       The  behavior  of wctype() depends on the LC_CTYPE category of the cur-
       rent locale.
