NAME
mvcur — output cursor movement commands to the terminal
SYNOPSIS
#include <curses.h>
int mvcur(int oldrow, int oldcol, int newrow, int newcol);
DESCRIPTION
The
mvcur()
function outputs one or more commands to the terminal that move the terminal's
cursor to (newrow, newcol), an absolute position on the terminal
screen. The (oldrow, oldcol) arguments specify the former cursor
position. Specifying the former position is necessary on terminals that do
not provide coordinate-based movement commands. On terminals that provide
these commands, Curses
may select a more efficient way to move the cursor based on the former
position. If (newrow, newcol) is not a valid address for the
terminal in use,
mvcur()
fails. If (oldrow, oldcol) is the same as (newrow,
newcol), then
mvcur()
succeeds without taking any action. If
mvcur()
outputs a cursor movement command, it updates its information concerning the
location of the cursor on the terminal.
RETURN VALUE
Upon successful completion,
mvcur()
returns OK.
Otherwise, it returns ERR.
ERRORS
No errors are defined.
APPLICATION USAGE
After use of
mvcur(),
the model Curses
maintains of the state of the terminal might not match the actual state of the
terminal. The application should touch and refresh the window before resuming
conventional use of Curses.
