.SH DESCRIPTION
|
|
The \fBprintw\fR, \fBwprintw\fR, \fBmvprintw\fR and \fBmvwprintw\fR
|
|
routines are analogous to \fBprintf\fR [see \fBprintf\fR(3)]. In
|
|
effect, the string that would be output by \fBprintf\fR is output
|
|
instead as though \fBwaddstr\fR were used on the given window.
|
|
.PP
|
|
The \fBvwprintw\fR and \fBwv_printw\fR routines are analogous
|
|
to \fBvprintf\fR [see \fBprintf\fR(3)]
|
|
and perform a \fBwprintw\fR using a variable argument list.
|
|
The third argument is a \fBva_list\fR, a pointer to a
|
|
list of arguments, as defined in \fB<stdarg.h>\fR.
|
|
.SH RETURN VALUE
|
|
Routines that return an integer return \fBERR\fR upon failure and \fBOK\fR
|
|
(SVr4 only specifies "an integer value other than \fBERR\fR") upon successful
|
|
completion.
|
|
.PP
|
|
X/Open defines no error conditions.
|
|
In this implementation,
|
|
an error may be returned if it cannot allocate enough memory for the
|
|
buffer used to format the results.
|
|
It will return an error if the window pointer is null.
|
|
.SH PORTABILITY
|
|
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\fBvwprintw\fR is marked TO BE WITHDRAWN, and is to be replaced by a function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
|
|
including \fB<varargs.h>\fR, which
|
|
cannot be used in the same file as \fB<stdarg.h>\fR.
|
|
This implementation uses \fB<stdarg.h>\fR for both, because that header
|
|
is included in \fB<curses.h\fR>.
