.SH DESCRIPTION
.SS refresh/wrefresh
The \fBrefresh\fP and \fBwrefresh\fP routines (or \fBwnoutrefresh\fP and
enabled, the physical cursor of the terminal is left at the location of the
cursor for that window.
.SS wnoutrefresh/doupdate
-.PP
The \fBwnoutrefresh\fP and \fBdoupdate\fP routines allow multiple updates with
more efficiency than \fBwrefresh\fP alone.
In addition to all the window
structures, \fBcurses\fP keeps two data structures representing the terminal
screen:
.bP
-a \fIphysical screen\fP, describing what is actually on the screen, and
+a \fIphysical screen\fP,
+describing what is actually on the screen, and
.bP
-a \fIvirtual screen\fP, describing what the programmer wants to have on the screen.
+a \fIvirtual screen\fP,
+describing what the programmer wants to have on the screen.
.PP
The routine \fBwrefresh\fP works by
.bP
(But see the section on \fBPORTABILITY\fP below for a warning about
exploiting this behavior.)
.SS wredrawln/redrawwin
-.PP
The \fBwredrawln\fP routine indicates to \fBcurses\fP that some screen lines
are corrupted and should be thrown away before anything is written over them.
It touches the indicated lines (marking them changed).
Instead, you can do an explicit \fBtouchwin\fP before the
\fBwnoutrefresh\fP call to guarantee an entire-contents copy anywhere.
