/**************************************************************************
* This is the function prototype declaration for the mousedrv module: *
* *
* W A R N I N G : This module assumes mouse driver was installed using *
* one of the following program: mouse.com or mouse.sys. *
* *
* This module can be compiled in any model (tiny..huge) *
* *
* The following routines are available: *
* 1. MouseDetect() - returns TRUE if mouse detected in system. *
* 2. MouseInit() - must be called first before any other call. *
* 3. MouseShowCorsur() - show mouse cursor. *
* 4. MouseHideCorsur() - hide mouse cursor. *
* 5. MouseQueryBuffer() - returns event ring buffer status. *
* 6. MouseQueryDataBuffer() - returns event ring buffer data status. *
* 7. MouseGetBuffer() - returns next event from ring buffer. *
* 8. MouseFlushBuffer() - clear all data currently in buffer. *
* 9. MouseClose() - must be called last before application program dies. *
* *
* Note that as the mouse driver is used asyncronically (i.e. interrupts) *
* fail to call MouseInit() at the begining or even worse, call *
* MouseClose() in the end is an invitation for total system disaster! *
* *
* Gershon Elber Aug. 88 *
