Specifies the class that you are interested in.
You can pass 
.ZN TileShape , 
.ZN CursorShape , 
or 
.ZN StippleShape .
.IP \fIdisplay\fP 1i
Specifies the connection to the X server.
.IP \fIwidth\fP 1i

.SH DESCRIPTION
The
.ZN XQueryBestSize
function returns the best or closest size to the specified size.
For 
.ZN CursorShape ,
this is the largest size that can be fully displayed on the screen specified by
which_screen.
For 
.ZN TileShape ,
this is the size that can be tiled fastest.
For 
.ZN StippleShape ,
this is the size that can be stippled fastest.
For 
.ZN CursorShape ,
the drawable indicates the desired screen.
For 
.ZN TileShape 
and 
.ZN StippleShape ,
the drawable indicates the screen and possibly the window class and depth.
An 
.ZN InputOnly 
window cannot be used as the drawable for 
.ZN TileShape
or 
.ZN StippleShape ,
or a
.ZN BadMatch 
error results.
.LP
.ZN XQueryBestSize
can generate
.ZN BadDrawable ,
.ZN BadMatch ,
and
.ZN BadValue 
errors.
.LP
The
.ZN XQueryBestTile
function returns the best or closest size, that is, the size that can be
tiled fastest on the screen specified by which_screen.
The drawable indicates the screen and possibly the window class and depth.
If an 
.ZN InputOnly 
window is used as the drawable, a 
.ZN BadMatch 
error results.
.LP
.ZN XQueryBestTile
can generate
.ZN BadDrawable
and
.ZN BadMatch 
errors.
.LP
The
.ZN XQueryBestStipple
function returns the best or closest size, that is, the size that can be
stippled fastest on the screen specified by which_screen.
The drawable indicates the screen and possibly the window class and depth.
If an
.ZN InputOnly
window is used as the drawable, a
.ZN BadMatch
error results.
.LP
.ZN XQueryBestStipple
can generate
.ZN BadDrawable
and
.ZN BadMatch 
errors.
.SH DIAGNOSTICS
.TP 1i
.ZN BadMatch
An
.ZN InputOnly
window is used as a Drawable.
.TP 1i
.ZN BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.
.TP 1i
.ZN BadMatch
The values do not exist for an
.ZN InputOnly
window.
.TP 1i
.ZN BadValue
Some numeric value falls outside the range of values accepted by the request.
Unless a specific range is specified for an argument, the full range defined
by the argument's type is accepted.  Any argument defined as a set of
alternatives can generate this error.
