+.SH NAME
+iswspace \- test for a white-space wide-character code
+.SH SYNOPSIS
+.LP
+\fB#include <wctype.h>
+.br
+.sp
+int iswspace(wint_t\fP \fIwc\fP\fB);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fIiswspace\fP() function shall test whether \fIwc\fP is a wide-character
+code representing a character of class
+\fBspace\fP in the program's current locale; see the Base Definitions
+volume of IEEE\ Std\ 1003.1-2001, Chapter 7, Locale.
+.LP
+The \fIwc\fP argument is a \fBwint_t\fP, the value of which the application
+shall ensure is a wide-character code
+corresponding to a valid character in the current locale, or equal
+to the value of the macro WEOF. If the argument has any other
+value, the behavior is undefined.
+.SH RETURN VALUE
+.LP
+The \fIiswspace\fP() function shall return non-zero if \fIwc\fP is
+a white-space wide-character code; otherwise, it shall
+return 0.
+.SH ERRORS
+.LP
+No errors are defined.
+.LP
+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+To ensure applications portability, especially across natural languages,
+only this function and those listed in the SEE ALSO
+section should be used for classification of wide-character codes.
+.SH RATIONALE
+.LP
+None.
+.SH FUTURE DIRECTIONS
+.LP
+None.
