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 guaran‐
       tee  movement to the next character, if the cursor was originally posi‐
       tioned 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.

ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:


       tab()  box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) ATTRIBUTE TYPEAT‐

NOTES
       The header file <curses.h>  automatically  includes  the  header  files
       <stdio.h> , <unctrl.h> and <widec.h>.


       Note that movenextch(), moveprevch(), and adjcurspos() may be macros.
