.SH DESCRIPTION
.sp
.LP
The \fBvw_printw()\fR function achieves the same effect as
\fBwprintw\fR(3XCURSES) using a variable argument list. The third argument is a
\fBva_list\fR, as defined in <\fBstdarg.h\fR>.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBvw_printw()\fR returns \fBOK\fR. Otherwise, it
returns \fBERR\fR.
.SH ERRORS
.sp
.LP
No errors are defined.
.SH USAGE
.sp
.LP
The \fBvw_printw()\fR function is preferred over \fBvwprintw\fR(3XCURSES). The
use of the \fBvwprintw()\fR and \fBvw_printw()\fR in the same file will not
work, due to the requirements to include <\fBvarargs.h\fR> and
<\fBstdarg.h\fR>, which both contain definitions of \fBva_list\fR.
