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.
