<DT><B>Description</B><DD><P>Load a mouse driver into memory and initialize it. The
|
|
function returns an error code that tells if the call has been successful. The
|
|
<CODE>mouse_callbacks</CODE> structure passed as first parameter contains pointers to
|
|
routines needed to move or hide/show the mouse pointer. Defaults for these
|
|
routines are supplied by the library, so if you can live with these defaults
|
|
(which are platform specific), just pass a pointer to <CODE>mouse_def_callbacks</CODE>.</P>
|
|
<DT><B>Limits</B><DD><P>
|
|
<UL>
|
|
<LI>The driver is loaded by name, so currently you must know the type of
|
|
mouse that should be supported. There is no autodetect capability.</LI>
|
|
<LI>Not all drivers are able to detect if the supported hardware is really
|
|
present.</LI>
|
|
<LI>After installing a driver, the mouse cursor is hidden.</LI>
|
|
<LI>The function is only available as fastcall function, so it may only be
|
|
used in presence of a prototype.</LI>
