/*----------------------------------------------------------------------------+
|
|   The following functions provide initialization routines for both the
|   transport demux driver, and the hardware.  xp0_init() is called to
|   initialize the driver and transport hardware.  The calling program must
|   supply the amount of memory reserved for the transport demux queues.
|   The space may be allocated on the heap (using malloc) or allocated via
|   a predetermined memory map.  The queue address must be aligned on a
|   16 MByte boundary if the pre-assigned address is used (queue_mode=0).
|
|   The error codes for all transport demux errors are mapped to a text
|   description using the xp0_get_error_msg() function.
