-\fBwrefresh\fR - refresh \fBcurses\fR windows and lines
-\fBint wrefresh(WINDOW *win);\fR
-\fBint wnoutrefresh(WINDOW *win);\fR
-\fBint redrawwin(WINDOW *win);\fR
-\fBint wredrawln(WINDOW *win, int beg_line, int num_lines);\fR
-The \fBrefresh\fR and \fBwrefresh\fR routines (or \fBwnoutrefresh\fR and
-\fBdoupdate\fR) must be called to get actual output to the terminal, as other
-routines merely manipulate data structures.
-The routine \fBwrefresh\fR copies
-the named window to the physical terminal screen, taking into account what is
-already there to do optimizations.
-The \fBrefresh\fR routine is the
-same, using \fBstdscr\fR as the default window.
-Unless \fBleaveok\fR has been
-enabled, the physical cursor of the terminal is left at the location of the
-cursor for that window.
-The \fBwnoutrefresh\fR and \fBdoupdate\fR routines allow multiple updates with
-more efficiency than \fBwrefresh\fR alone.
-In addition to all the window
-structures, \fBcurses\fR keeps two data structures representing the terminal
-screen: a physical screen, describing what is actually on the screen, and a
-virtual screen, describing what the programmer wants to have on the screen.
-The routine \fBwrefresh\fR works by first calling \fBwnoutrefresh\fR, which
-copies the named window to the virtual screen, and then calling \fBdoupdate\fR,
-which compares the virtual screen to the physical screen and does the actual
-If the programmer wishes to output several windows at once, a series
-of calls to \fBwrefresh\fR results in alternating calls to \fBwnoutrefresh\fR
-and \fBdoupdate\fR, causing several bursts of output to the screen.
-calling \fBwnoutrefresh\fR for each window, it is then possible to call
-\fBdoupdate\fR once, resulting in only one burst of output, with fewer total
-characters transmitted and less CPU time used.
-If the \fIwin\fR argument to
-\fBwrefresh\fR is the global variable \fBcurscr\fR, the screen is immediately
-cleared and repainted from scratch.
-The phrase "copies the named window to the virtual screen" above is ambiguous.
-What actually happens is that all \fItouched\fR (changed) lines in the window
-are copied to the virtual screen.
-This affects programs that use overlapping
-windows; it means that if two windows overlap, you can refresh them in either
-order and the overlap region will be modified only when it is explicitly
-(But see the section on \fBPORTABILITY\fR below for a warning about
-exploiting this behavior.)
-The \fBwredrawln\fR routine indicates to \fBcurses\fR 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).
-The routine \fBredrawwin\fR() touches the entire window.
-.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
-X/Open does not define any error conditions.
-In this implementation
-returns an error
-if the window pointer is null, or
-if the window is really a pad.
-returns an error
-if the associated call to \fBtouchln\fP returns an error.
-Note that \fBrefresh\fR and \fBredrawwin\fR may be macros.
-The XSI Curses standard, Issue 4 describes these functions.
-Whether \fBwnoutrefresh()\fR copies to the virtual screen the entire contents
-of a window or just its changed portions has never been well-documented in
-historic curses versions (including SVr4).
-It might be unwise to rely on
-either behavior in programs that might have to be linked with other curses
-Instead, you can do an explicit \fBtouchwin()\fR before the
-\fBwnoutrefresh()\fR call to guarantee an entire-contents copy anywhere.
