Odd thing. I posted in the Solaris forum, new user, just asking for a bit of advice. Nothing too complicated. As of this post there have been 140 views and zero replies. So that got me thinking, is this normal? I had a look around, and I see the same thing on many other threads, and in other...

wchar.h

wchar.h(3HEAD)							      Headers							    wchar.h(3HEAD)

NAME

       wchar.h, wchar - wide-character handling

SYNOPSIS

       #include <wchar.h>

DESCRIPTION

       The <wchar.h> header defines the following types:

       wchar_t	    As described in <stddef.h>.

       wint_t	    An integer type capable of storing any valid value of wchar_t or WEOF.

       wctype_t     A scalar type of a data object that can hold values which represent locale-specific character classification.

       mbstate_t    An	object type other than an array type that can hold the conversion state information necessary to convert between sequences
		    of (possibly multi-byte) characters and wide characters.  If a codeset is being used such that  an mbstate_t needs to preserve
		    more than two levels of reserved state, the results are unspecified.

       FILE	    As described in <stdio.h>.

       size_t	    As described in <stddef.h>.

       va_list	    As described in <stdarg.h>.

       The  implementation  supports  one or more programming environments in which the width of wint_t is no greater than the width of type long.
       The names of these programming environments can be obtained using the confstr(3C) function or the getconf(1) utility.

       The <wchar.h> header defines the following macros:

       WCHAR_MAX    The maximum value representable by an object of type wchar_t.

       WCHAR_MIN    The minimum value representable by an object of type wchar_t.

       WEOF	    Constant expression of type wint_t that is returned by several WP functions to indicate end-of-file.

       NULL	    As described in <stddef.h>.

       The tag tm is declared as naming an incomplete structure type, the contents of which are described in the header <time.h>.

       Inclusion of the <wchar.h> header can make visible all symbols from the headers <ctype.h>,  <string.h>, <stdarg.h>, <stddef.h>,	<stdio.h>,
       <stdlib.h>, and <time.h>.
