+ SVr2 documented <B>printw</B>, <B>wprintw</B> tersely as "printf on <I>stdscr</I>" and
+ tersely as "printf on <I>win</I>", respectively.
+
+ SVr3 added <B>mvprintw</B>, and <B>mvwprintw</B>, with a three-line summary saying
+ that they were analogous to <B>printf(3)</B>, explaining that the string which
+ would be output from <B>printf(3)</B> would instead be output using <B>waddstr</B> on
+ the given window. SVr3 also added <B>vwprintw</B>, saying that the third pa-
+ rameter is a <B>va_list</B>, defined in <varargs.h>, and referring the reader
+ to the manual pages for <I>varargs</I> and <I>vprintf</I> for detailed descriptions.
+
+ SVr4 added no new variations of <B>printw</B>, but provided for using
+ <varargs.h> or <stdarg.h> to define the <B>va_list</B> type.
+
+ X/Open Curses added <B>vw_printw</B> to replace <B>vwprintw</B>, stating that its
+ <B>va_list</B> definition requires <stdarg.h>.

+ In this implementation, <B>vw_printw</B> and <B>vwprintw</B> are equivalent, to sup-
+ port legacy applications. However, the latter (<B>vwprintw</B>) is obsolete:
+
+ <B>o</B> The XSI Curses standard, Issue 4 described these functions. The
+ function <B>vwprintw</B> is marked TO BE WITHDRAWN, and is to be replaced
+ by a function <B>vw_printw</B> using the <B><stdarg.h></B> interface.
+
+ <B>o</B> The Single Unix Specification, Version 2 states that <B>vw_printw</B> is
+ preferred to <B>vwprintw</B> since the latter requires including
+ <B><varargs.h></B>, which cannot be used in the same file as <B><stdarg.h></B>.
+ This implementation uses <B><stdarg.h></B> for both, because that header
+ is included in <B><curses.h</B>>.
+
+ <B>o</B> X/Open Curses, Issue 5 (December 2007) marked <B>vwprintw</B> (along with
+ <B>vwscanw</B> and the termcap interface) as withdrawn.
