.SH DESCRIPTION
+.SS newwin
Calling \fBnewwin\fR creates and returns a pointer to a new window with the
given number of lines and columns.
The upper left-hand corner of the window is
.RE
.PP
A new full-screen window is created by calling \fBnewwin(0,0,0,0)\fR.
+.SS delwin
.PP
Calling \fBdelwin\fR deletes the named window, freeing all memory
associated with it (it does not actually erase the window's screen
image).
Subwindows must be deleted before the main window can be deleted.
+.SS mvwin
.PP
Calling \fBmvwin\fR moves the window so that the upper left-hand
corner is at position (\fIx\fR, \fIy\fR).
If the move would cause the window to be off the screen,
it is an error and the window is not moved.
Moving subwindows is allowed, but should be avoided.
+.SS subwin
.PP
Calling \fBsubwin\fR creates and returns a pointer to a new window
with the given number of lines, \fInlines\fR, and columns, \fIncols\fR.
When using this routine, it is necessary to call
\fBtouchwin\fR or \fBtouchline\fR on \fIorig\fR before calling
\fBwrefresh\fR on the subwindow.
+.SS derwin
.PP
Calling \fBderwin\fR is the same as calling \fBsubwin,\fR except that
\fIbegin\fR_\fIy\fR and \fIbegin\fR_\fIx\fR are relative to the origin
This routine is used to display different
parts of the parent window at the same physical position on the
screen.
+.SS dupwin
.PP
Calling \fBdupwin\fR creates an exact duplicate of the window \fIwin\fR.
+.SS wsyncup
.PP
Calling \fBwsyncup\fR touches all locations in ancestors of \fIwin\fR that are
changed in \fIwin\fR.
If \fBsyncok\fR is called with second argument
\fBTRUE\fR then \fBwsyncup\fR is called automatically whenever there is a
change in the window.
+.SS wsyncdown
.PP
The \fBwsyncdown\fR routine touches each location in \fIwin\fR that has been
touched in any of its ancestor windows.
This routine is called by
\fBwrefresh\fR, so it should almost never be necessary to call it manually.
+.SS wcursyncup
.PP
The routine \fBwcursyncup\fR updates the current cursor position of all the
ancestors of the window to reflect the current cursor position of the
.PP
Note that \fBsyncok\fR may be a macro.
.SH BUGS
-The subwindow functions (\fIsubwin\fR, \fIderwin\fR, \fImvderwin\fR,
+The subwindow functions (\fBsubwin\fR, \fBderwin\fR, \fBmvderwin\fR,
\fBwsyncup\fR, \fBwsyncdown\fR, \fBwcursyncup\fR, \fBsyncok\fR) are flaky,
incompletely implemented, and not well tested.
