WCTYPE(3)	      DragonFly 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
     wctype() 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.

SEE ALSO
     iswctype(3), setlocale(3), towctrans(3), wctrans(3)

STANDARDS
     The wctype() function conforms to ISO/IEC 9899/AMD1:1995 (``ISO C90,
     Amendment 1'').
