.SH DESCRIPTION
The
.ZN XRecolorCursor
function changes the color of the specified cursor, and
if the cursor is being displayed on a screen,
the change is visible immediately.
The pixel members of the
.ZN XColor
structures are ignored; only the RGB values are used.
.LP
.ZN XRecolorCursor
can generate a
.ZN BadCursor 
error.
.LP
The
.ZN XFreeCursor
function deletes the association between the cursor resource ID 
and the specified cursor.
The cursor storage is freed when no other resource references it.
The specified cursor ID should not be referred to again.
.LP
.ZN XFreeCursor
can generate a
.ZN BadCursor 
error.
.LP
Some displays allow larger cursors than other displays.
The
.ZN XQueryBestCursor
function provides a way to find out what size cursors are actually
possible on the display.
.IN "Cursor" "limitations" 
It returns the largest size that can be displayed.
Applications should be prepared to use smaller cursors on displays that
cannot support large ones.
.LP
.ZN XQueryBestCursor
can generate a
.ZN BadDrawable 
error.
.SH DIAGNOSTICS
.TP 1i
.ZN BadCursor
A value for a Cursor argument does not name a defined Cursor.
.TP 1i
.ZN BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.
