SYNOPSIS

   Remarks
       These functions are compliant with the XPG4 Worldwide Portability Interface wide-character classification  functions.   They  parallel  the
       8-bit character classification functions defined in ctype(3C).

DESCRIPTION

       These  functions classify wide character values according to the rules of the coded character set identified by the last successful call to
       (see setlocale(3C)).

       If has not been called successfully, characters are classified according to the rules of the default ASCII 7-bit coded character  set  (see
       setlocale(3C)).

       Each of the classification functions is a predicate that returns non-zero for true, zero for false.

       is  defined  for valid character class names as defined in the current locale.  charclass is a string identifying a generic character class
       for which codeset-specific type information is required.  The following class names are defined in  all	locales:  and  User-defined  class
       names may be specified if supported by the current locale as defined by (see setlocale(3C)).  returns a value of type that can be used in a
       subsequent call to or if charclass is not valid in the current locale.

       The classification functions return non-zero under the following circumstances, and zero otherwise:

	      wc		  has the property defined by prop.

	      wc		  is a letter.

	      wc		  is a blank character; that is a space or tab.

	      wc		  is an uppercase letter.

	      wc		  is a lowercase letter.

	      wc		  is a decimal digit (in ASCII: characters [0-9]).

	      wc		  is a hexadecimal digit (in ASCII: characters [0-9], [A-F] or [a-f]).

	      wc		  is an alphanumeric (letters or digits).

	      wc		  is a character that creates "white space" in displayed text (in ASCII: space, tab,  carriage	return,  new-line,
				  vertical tab, and form-feed).

	      wc		  is a punctuation character (in ASCII: any printing character except the space character(040), digits, letters).

	      wc		  is a printing character.

	      wc		  is a visible character (in ASCII: printing characters, excluding the space character(040)).

	      wc		  is a control character (in ASCII: character codes less than 040 and the delete character(0177)).

       If the argument to any of these functions is outside the domain of the function, the result is 0 (false).

       Definitions for these functions and the types and are provided in the header.

EXTERNAL INFLUENCES

   Locale
       The category determines the classification of character type.

   International Code Set Support
       Single-byte and multibyte character code sets are supported.
