Hi all,
I don't know if this is the correct list. If it's not I'm sorry.
I have kind of a weird question. I'm playing this game iRacing which exposed it's api via named memory map ( https://github.com/meltingice/node-iracing/blob/master/lib/irsdk_utils.cpp).
Is there a way I can access that named memory-mapped file via Linux? I did some Googling and I don't think it's possible but I thought I made sure to ask around here. If that isn't possible I think I'll write a simple program that would run under wine and expose that data in a Linux-friendly manner.

Just to clarify: the game runs under wine (crossover) on my Linux box.

The syscalls I need translated to linux are: - OpenFileMappingW - MapViewOfFile
Today I found out about winelib. I guess I could give that a go.

Hey Leon, sorry I missed your earlier emails.
I'm the primary developer of the official iRacing Linux port by CodeWeavers, and I actually play it myself. I don't have the time to dig into this right now, but I'm definitely interested in what you find out and could maybe help with some questions. Depending on what you end up with, we could maybe integrate your work back into the official port.
I think what you want to do, at a high level, is find out how Wine implements those methods on Linux. Then figure out how a Linux-native application could hook into that implementation. Wine is, after all, just a program running on Linux like any other.
Alternatively, you could write a win32 application and use those Wine APIs to access the memory and do what you want, like you said.

Wine implements those two calls and maps them to the equivalent POSIX functions. Yes, building a Winelib program is the right way to go. It can use the Win32 functions and normal Linux functions at the same time. It does depend on the Wine runtime environment though. Note that your game and your winelib application have to run in the same wine prefix.
In theory you could probably use plain mmap in some way, but then you have to know how Wine maps the Windows object to it's POSIX equivalent.
