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);
DESCRIPTION
movenextch() 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 movement 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.
