Ok, so I understand from your answer that only one instance of Egg object is allocated in the program static memory area, even when an egg class object is a member of that class.

iocallback
IOCallback(3I) InterViews Reference Manual IOCallback(3I) NAME
IOCallback - generic callback class for readers, writers, or I/O exception handlers SYNOPSIS
#include <Dispatch/iocallback.h> DESCRIPTION
For convenience, the macros defined in iocallback.h allow the user to define an iohandler which does nothing more than call an arbitrary object's member function. The actual code to read data from a file descriptor, write data to a file descriptor, handle an I/O exception on a file descriptor, or handle a timer's expiration can reside in any arbitrary class rather than in the iohandler. MACROS
declareIOCallback(T) Declare an iocallback type for the given class type T. implementIOCallback(T) Emit code at this point to implement the iocallback's member functions. IOCallback(T)* instance = new IOCallback(T)(...) Define an instance of the iocallback type for the given class type T. CONSTRUCTORS
typedef int T::IOReady(T)(int fd) typedef void T::IOTimer(T)(long sec, long usec) IOCallback(T)(T*, IOReady(T)* in, IOReady(T)* out = nil, IOReady(T)* ex = nil) IOCallback(T)(T*, IOTimer(T)*, IOReady(T)* in = nil, IOReady(T)* out = nil, IOReady(T)* ex = nil) Construct an instance of the iocallback type that will call the given member functions of the given class type T's instance. Note that you do not have to use the IOReady(T) or IOTimer(T) macros; rather, you only have to pass the address of a T member function, such as &T::inputReady. SEE ALSO
