vcan_pb_dump
============

Here is the definition::

  typedef struct
    { byte  data[16] CDEP_NOALIGN_ATTR;
      long  offset   CDEP_NOALIGN_ATTR;
      long  datasize CDEP_NOALIGN_ATTR;
    } vcan_pb_dump;

This driver-call-sub-structure is used to dump a part of the so called
'parameter buffer' of the VME-CAN2 card. It is used in conjunction with the
``VCAN_READ_OBJ_CTRL`` sub-function. The buffer has a size of 256 bytes, but
only 16 bytes can be read from this buffer at a time.

data
  This array of 16 bytes contains a part of the parameter-buffer of the
  VME-CAN2 card after the execution of the command.

offset
  This is the offset into the parameter-buffer, since only a part of the
  buffer can be read at a time. The first byte of the buffer has an offset
  of 0.

datasize
  This is the size of the data that has to be read. This number can only be
  in the range of 1 to 16. Note that it is an error, to read over the end of
  the internal parameter-buffer, e.g. when offset`` is 250, ``datasize``
  must not be greater than 6.
