 Name:         »XHDriverSpecial« - Use driver-specific extensions.

 Opcode:       13

 Syntax:       LONG XHDriverSpecial ( ULONG key1, ULONG key2, UWORD 
               subopcode, VOID *data );

 Description:  This opcode may be used for driver-specific extensions. 
               It's up to the driver how to interpret the arguments in 
               subopcode and data. key1 and key2 are used to specify 
               for which driver the call is intended:

               key1 should contain four printable ASCII characters, 
               key2 a random ULONG value (example: date of definition 
               in BCD format).

               Note: OPTIONAL function, may return EINVFN.

 Return value: XHDI error-codes.

 Group:        XHDI functions
