"Basic Object Oriented Programming System for Intuition).

or by a pointer to its definition (if it's a private class). If
classPtr is NULL, classID is used.

happen to have a pointer to it)

Initial attributes. Read the documentation of the class
carefully to find out which attributes must be specified
here and which can.
RESULT
A BOOPSI object which can be manipulated with general functions and
which must be disposed with DisposeObject() later.
NOTES
This functions send OM_NEW to the dispatcher of the class.
