.SH NAME
curs_alecompat, movenextch, wmovenextch, moveprevch, wmoveprevch, adjcurspos,
wadjcurspos \- these functions are added to ALE curses library for moving the
cursor by character.

.SH DESCRIPTION
.sp
.LP
\fBmovenextch()\fR and \fBwmovenextch()\fR 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 (\fB++x\fR) does not guarantee movement
to the next character, if the cursor was originally positioned on a
multicolumn character. \fBgetyx\fR(3CURSES) can be used to find the new
position.
.sp
.LP
\fBmoveprevc()\fR and \fBwmoveprevch()\fR routines are the opposite of
\fBmovenextch()\fR and \fBwmovenextch()\fR, moving the cursor to the left-most
column of the previous character.
.sp
.LP
\fBadjcurspos()\fR and \fBwadjcurspos()\fR 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.
.SH RETURN VALUE
.sp
.LP
All routines return the integer \fBERR\fR upon failure and an integer value
other than \fBERR\fR upon successful completion.
.SH ATTRIBUTES
