.SH DESCRIPTION
The display server shall redraw the window's,
whose ID is specified in the
.I window
field, background in the rectangle specified
by the
.IR x ,
.IR y ,
.IR width ,
and
.IR height .
.PP
The
.I x
and
.I y
fields specify the rectangles top left corner
as pixels offset right of and down from the
window's top left corner. The
.I width
and
.I height
fields specify the width and height, in
pixels, of the rectangle, however the
specified
.I width
is 0, than the rectangle stretches to the
right edge of the window, and if the specified
.I height
is 0, than the rectangle stretches to the
bottom edge of the window.
.PP
If the
.I exposures
field is set to
.IR LIBAXL_TRUE ,
one or more
.I LIBAXL_EVENT_EXPOSE
events are generated for regions of the rectangle
that are either visible or are being retained in
a backing store.
.PP
The value of the
.I opcode
field shall be
.I LIBAXL_REQUEST_CLEAR_AREA
to signify that the request is of the

.PP
Other fields are filled in automatically by the
.BR libaxl_send_request (3)
function.
