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 is marked TO BE WITHDRAWN, and is to be replaced by a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) is obsolete:
