.SH SYNOPSIS
.PP
The routine \fBchgat\fR changes the attributes of a given number of characters
starting at the current cursor location of \fBstdscr\fR. It does not update
-the cursor and does not perform wrapping. A character count of -1 or greater
+the cursor and does not perform wrapping. A character count of \-1 or greater
than the remaining window width means to change attributes all the way to the
end of the current line. The \fBwchgat\fR function generalizes this to any
window; the \fBmvwchgat\fR function does a cursor move before acting. In these
functions, the color argument is a color-pair index (as in the first argument
of \fIinit_pair\fR, see \fBcurs_color\fR(3X)). The \fBopts\fR argument is not
presently used, but is reserved for the future (leave it \fBNULL\fR).
-Note that changing the attributes does not imply
-that a subsequent \fBrefresh\fR will update the screen to match,
-since the character values are not modified.
-Use \fBtouchwin\fR to force the screen to match the updated attributes.
.SS Attributes
The following video attributes, defined in \fB<curses.h>\fR, can be passed to
the routines \fBattron\fR, \fBattroff\fR, and \fBattrset\fR, or OR'd with the
\fBwattr_get\fR, \fBwattr_set\fR. These are intended to work with
a new series of highlight macros prefixed with \fBWA_\fR.
.PP
+Older versions of this library did not force an update of the screen
+when changing the attributes.
+Use \fBtouchwin\fR to force the screen to match the updated attributes.

This implementation returns an error

The \fBwcolor_set\fP function returns an error if the color pair parameter
-is outside the range 0..COLOR_PAIRS-1.
