+.Nm wchar.h
+.Nd wide character & wide character string manipulation
+.\"
+.Sh SYNOPSIS
+.In wchar.h
+.\"
+.Sh DESCRIPTION
+The
+.In wchar.h
+header provides functions for manipulating wide character strings" "for
+converting between wide characters and multibyte character sets" "for 
+manipulating wide character strings" "and for wide character oriented input and 
+output.
+.\"
+.Ss Types & Definitions
+The type
+.Vt size_t
+and macro
+.Dv NULL
+shall be defined as in
+.In stddef.h .
+.Pp
+The type
+.Vt wchar_t
+shall be defined as an integral type capable of representing any wide character
+in the implementation defined encoding. The type
+.Vt wint_t
+shall be defined as an integral type capable of representing any wide character
+in the implementation defined encoding" "plus the distinct value given by
+.Dv WEOF ,
+which evaluates to a constant expression of type
+.Vt wint_t
+which does not correspond to any character in the implementation defined 
+character set. The macros 
+.Dv WCHAR_MIN
+and
+.Dv WCHAR_MAX
+shall be defined as in
+.In stdint.h .
+.Pp
+The type
+.Vt mbstate_t
+shall be a complete non-array object type used for the storage of the state of
+a multibyte to wide character conversion.
+.Pp
+The type
+.Vt struct tm
+shall be defined as an incomplete type" "a full definition of wich can be found 
+in
+.In time.h .
