curs_alecompat(3CURSES) Curses Library Functions curs_alecompat(3CURSES)NAME
curs_alecompat, movenextch, wmovenextch, moveprevch, wmoveprevch,
adjcurspos, wadjcurspos - these functions are added to ALE curses
library for moving the cursor by character.
SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library .. ]
#include <curses.h>
int movenextch(void);
int wmovenextch(WINDOW *win);
int moveprevch(void);
int wmoveprevch(WINDOW *win);
int adjcurspos(void);
int wadjcurspos(WINDOW *win);
DESCRIPTIONmovenextch() and wmovenextch() move the cursor to the next character to
the right. If the next character is a multicolumn character, the cursor
is positioned on the first (left-most) column of that character. The
new cursor position will be on the next character, even if the cursor
was originally positioned on the left-most column of a multicolumn
character.
Note that the simple cursor increment (++x) does not guarantee move‐
ment to the next character, if the cursor was originally positioned on
a multicolumn character. getyx(3CURSES) can be used to find the new
position.
moveprevc() and wmoveprevch() routines are the opposite of
movenextch() and wmovenextch(), moving the cursor to the left-most
column of the previous character.
adjcurspos() and wadjcurspos() move the cursor to the first(left-most)
column of the multicolumn character that the cursor is presently on. If
the cursor is already on the first column, or if the cursor is on a
single-column character, these routines will have no effect.
RETURN VALUE
All routines return the integer ERR upon failure and an integer value
other than ERR upon successful completion.
