0.12.2 can't access shared memory from another process on Windows #82

Trying to open shared memory of third-party application that is created only as named object.

ShmemConf::new().os_id("TestNamedObject").open()

fails with OS error 2 (No such file or directory) because open_mapping tries to access non-existent %TEMP%\shared-memory-rs\TestNamedObject. It worked correctly in 0.11.

Thanks for submitting this issue. Like you said, this behaviour was introduced in 12.X on Windows in order to mimic how shared memory works on posix systems.

I agree that the crate should be able to handle shared memory mappings from external processes tho so a fix will have to be implemented to address this issue

This should now work on 0.12.3
