GetAttr -- Inquire the value of some attribute of an object. (V36)
attr = GetAttr( AttrID, Object, StoragePtr )
D0 D0 A0 A1
ULONG GetAttr( ULONG, APTR, ULONG * );
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.
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
Returns FALSE (0) if the inquiries of attribute are not provided
by the object's class.
This function invokes the OM_GET method of the object.
