I have a dll, which is loaded by the couple of processes. In that DLL source code I have an instance of global variable. Will this global variable be the same in all loaded processes ? Or will it be as the unique variable in each process ?

Only the code is shared between processes. – Hans Passant Dec 09 '13 at 16:04

Pretty sure it'd be unique to each process. – Danny Beckett Dec 09 '13 at 16:04

Normally it will be unique, though there are ways of making it shared. In Win16 they are shared though. – doynax Dec 09 '13 at 16:05

Each process should have its own copy of the variable. But you can make sure of that with a small test program that shouln't take more than 5 minutes to write. – Guntram Blohm Dec 09 '13 at 16:06

@Bathsheba - language is irrelevant, it is *operating system* which matters. – Chris Stratton Dec 09 '13 at 16:15

It will be unique to each process, unless (i) you've written explicit code to share inter-process or (ii) are still using a 16 bit dll.
