mvcur - output cursor movement commands to the terminal


#include <curses.h>

int mvcur(int oldrow, int oldcol, int newrow, int newcol);


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.


Upon successful completion, mvcur() returns OK. Otherwise, it returns ERR.


No errors are defined.


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.
