NAME
        GetAttr -- Inquire the value of some attribute of an object. (V36)

    SYNOPSIS
        attr = GetAttr( AttrID, object, storageptr )
        D0              D0      A0      A1

        ULONG GetAttr( ULONG, aptr, ulong * );

    FUNCTION
        Inquires from the specified object the value of the specified attribute.

        You always pass the address of a long variable, which will
        receive the same value that would be passed to SetAttrs() in
        the ti_Data portion of a tagitem element.  see the documentation
        for the class for exceptions to this general rule.

        Not all attributes will respond to this function.  Those that
        will are documented on a class-by-class basis.

    INPUTS
        AttrID = the attribute tag ID understood by the object's class
        object = abstract pointer to the boopsi object you are interested in
        StoragePtr = pointer to appropriate storage for the answer

    RESULT
        Returns FALSE (0) if the inquiries of attribute are not provided
        by the object's class.

    NOTES
        This function invokes the OM_GET method of the object.
