Sharing C++ Objects with virtual function table pointers
I am pondering the next question:
Can I safely sare objects that have virtual functions (i.e. have
virtual function table pointers) between two processes ?
Where will the pointers point to in each process ?
What I am afraid of is that in the creating process the pointer
will indeed point to the virtual function table, but in the
sharing process that pointer will point at junk.
Can anyone calm me or maybe confirm my fears ?
Thank you !
