.SH NAME
|
|
\fBoverlay\fR,
|
|
\fBoverwrite\fR,
|
|
\fBcopywin\fR - overlay and manipulate overlapped \fBcurses\fR windows
|

|
.SH SYNOPSIS
|
|
\fB#include <curses.h>\fR
|
|
.sp
|
|
\fBint overlay(const WINDOW *srcwin, WINDOW *dstwin);\fR
|
|
.br
|
|
\fBint overwrite(const WINDOW *srcwin, WINDOW *dstwin);\fR
|
|
.br
|
|
\fBint copywin(const WINDOW *srcwin, WINDOW *dstwin, int sminrow,\fR
|
|
\fBint smincol, int dminrow, int dmincol, int dmaxrow,\fR
|
|
\fBint dmaxcol, int overlay);\fR
|
|
.SH DESCRIPTION
|
|
The \fBoverlay\fR and \fBoverwrite\fR routines overlay \fIsrcwin\fR on
|
|
top of \fIdstwin\fR. \fIscrwin\fR and \fIdstwin\fR are not required
|
|
to be the same size; only text where the two windows overlap is
|
|
copied. The difference is that \fBoverlay\fR is non-destructive
|
|
(blanks are not copied) whereas \fBoverwrite\fR is destructive.
|
|
.PP
|
|
The \fBcopywin\fR routine provides a finer granularity of control over the
|
|
\fBoverlay\fR and \fBoverwrite\fR routines. Like in the \fBprefresh\fR
|
|
routine, a rectangle is specified in the destination window, (\fIdminrow\fR,
|
|
\fIdmincol\fR) and (\fIdmaxrow\fR, \fIdmaxcol\fR), and the upper-left-corner
|
|
coordinates of the source window, (\fIsminrow\fR, \fIsmincol\fR). If the
|
|
argument \fIoverlay\fR is \fBtrue\fR, then copying is non-destructive, as in
|
|
\fBoverlay\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,
|
|
\fBcopywin\fP,
|
|
\fBoverlay\fP and \fBoverwrite\fP return an error
|
|
if either of the window pointers are null, or
|
|
if some part of the window would be placed off-screen.
|
|
.SH NOTES
|
|
Note that \fBoverlay\fR and \fBoverwrite\fR may be macros.
|
|
.SH PORTABILITY
|
|
The XSI Curses standard, Issue 4 describes these functions (adding the const
|
|
qualifiers). It further specifies their behavior in the presence of characters
|
|
with multibyte renditions (not yet supported in this implementation).
