winebus.sys: Fix container detection

[redmcg]

msvcrt 'access' will return 0 if the file is present and readable

Nice catch.

FWIW this is not msvcrt's access but glibc's one. The code lives on the unix side.

Oops, of course; not sure what I was thinking.

A question unrelated to this PR: is there a way to disable the container when launching a game in Proton? I was just searching the code to see if there was an env variable or something that could be set - but you might know off the top of your head.

On Arch Linux there's a package named steam-native that install all the dependencies for Steam itself and runs things without the runtime:

$ cat $(which steam-native)
#!/bin/bash
export STEAM_RUNTIME=0
export STEAM_RUNTIME_HEAVY=0
# Workaround for dbus fatal termination related coredumps (SIGABRT)
# https://github.com/ValveSoftware/steam-for-linux/issues/4464
export DBUS_FATAL_WARNINGS=0
# Override some libraries as these are what games linked against.
export LD_LIBRARY_PATH="/usr/lib/steam:/usr/lib32/steam${LD_LIBRARY_PATH:+:}$LD_LIBRARY_PATH"
exec /usr/lib/steam/steam "$@"

It may do what you want. Just keep in mind that running Proton outside of the provided containers is unsupported.

Awesome - thanks for that - I'll take a look.
