VCAN_MAX_READ_OBJECTS
=====================

Here is the definition::

  #define VCAN_MAX_READ_OBJECTS 20

This constant defines the maximum number of objects that the
``VCAN_READ_MANY`` function can handle in one call. This is also a provision
against usage errors since an undefined array of object-id's given to the
``VCAN_READ_MANY`` function will probably exceed ``VCAN_MAX_READ_OBJECTS``
in it's length.
