 The XSI Curses standard, Issue 4 describes these functions.  The function
 \fBvwprintw\fR is marked TO BE WITHDRAWN, and is to be replaced by a function
 \fBvw_printw\fR using the \fB<stdarg.h>\fR interface.
+The Single Unix Specification, Version 2 states that
+\fBvw_printw\fR  is preferred to \fBvwprintw\fR since the latter requires
