Sharing memory between a Windows Wine process and a Linux process doesn't work

[skligys]

It looks to me that is just because on Windows files representing shmem objects go into

C:\Users\<user>\Temp\shared_memory-rs

and on Linux into

/dev/shm

Once I forced the Windows/Wine process to create a file in Z:\\dev\\shm, which in Wine corresponds to Linux's /dev/shm, sharing seems to work fine.

What do you think of a new wine feature where windows.rs get_tmp_dir() would just return Ok(PathBuf::from("Z:\\dev\\shm")) ?

Why would I want to do that? My use case:

• A Windows device-specific DLL creates frames, stores them in shared memory,
• A Linux app pulls them out of shared memory and visualizes them for diagnostics.
