Shared libraries on Linux only share read-only text and data, which should not be application-visible.
If you want to share state between processes, the library must explicitly set up a shared mapping - but of course a statically linked library can do this just as well.
- amscanne 13y agoYes, I know. My point was related to the terminology re: static, dynamic, shared, etc. A statically-linked library won't share any state with other users of the library. It's statically-linked into the binary. State will be shared only with the instances of the same binary.
- caf 13y agoIt is irrelevant whether the library is statically-linked into the binary or not - a statically-linked library can share state with instances of that library linked into other binaries just as easily as a dynamically-linked library can. In both cases the library must explicitly set up some shared state.
