NAME

   XDefineCursor, XUndefineCursor - define cursors

SYNTAX

   int XDefineCursor(Display *display, Window w, Cursor cursor);

   int XUndefineCursor(Display *display, Window w);

ARGUMENTS

   cursor    Specifies the cursor that is to be displayed or None.

   display   Specifies the connection to the X server.

   w         Specifies the window.

DESCRIPTION

   If a cursor is set, it will be used when the pointer is in the window.
   If the cursor is None, it is equivalent to XUndefineCursor.

   XDefineCursor can generate BadCursor and BadWindow errors.

   The XUndefineCursor function undoes the effect of a previous
   XDefineCursor for this window.  When the pointer is in the window, the
   parent's cursor will now be used.  On the root window, the default
   cursor is restored.

   XUndefineCursor can generate a BadWindow error.

DIAGNOSTICS

   BadAlloc  The server failed to allocate the requested resource or
             server memory.

   BadCursor A value for a Cursor argument does not name a defined Cursor.

   BadWindow A value for a Window argument does not name a defined Window.
