+.SS delwin
+Calling \fBdelwin\fP 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
+Calling \fBmvwin\fP moves the window so that the upper left-hand
+corner is at position (\fIx\fP, \fIy\fP).
+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
+Calling \fBsubwin\fP creates and returns a pointer to a new window
+with the given number of lines, \fInlines\fP, and columns, \fIncols\fP.
+The window is at position (\fIbegin\fR_\fIy\fP,
+\fIbegin\fR_\fIx\fP) on the screen.
+The subwindow shares memory with the window \fIorig\fP,
+so that changes made to one window
+will affect both windows.
+When using this routine, it is necessary to call
+\fBtouchwin\fP or \fBtouchline\fP on \fIorig\fP before calling
+\fBwrefresh\fP on the subwindow.
+.SS derwin
+Calling \fBderwin\fP is the same as calling \fBsubwin,\fP except that
+\fIbegin\fR_\fIy\fP and \fIbegin\fR_\fIx\fP are relative to the origin
+of the window \fIorig\fP rather than the screen.
+There is no difference between the subwindows and the derived windows.
