WCTYPE(3)               NetBSD Library Functions Manual              WCTYPE(3)


NAME

     wctype - get character class identifier by name


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <wctype.h>

     wctype_t
     wctype(const char *charclass);


DESCRIPTION

     The wctype() function returns a character class identifier corresponding
     to the locale-specific character class name charclass.  This identifier
     can be used in subsequent calls of iswctype().  The following names are
     defined in all locales:

           alnum alpha blank cntrl digit graph
           lower print punct space upper xdigit

     The behaviour of wctype() is affected by the LC_CTYPE category of the
     current locale.


RETURN VALUES

     wcttype() returns:

     0             If charclass does not correspond to a valid character class
                   name.

     non-zero      A character class identifier corresponding to charclass.

     Note: wctype_t is a scalar type, e.g., a pointer.


ERRORS

     No errors are defined.
