|
* Params : PUINT puiMsh_MsgMouseWheel - address of UINT to contain returned registered wheel message
|

|
|
* PUINT puiMsh_MsgScrollLines - address of UINT to contain Scroll lines registered message

* Note : The return value for pf3DSupport and piScrollLines is dependant
|
|
* on the POINT32 module. If POINT32 module is not running then
