The was duplicated in the XInput2 code, but taking an SDL_VideoData parameter instead of SDL_VideoDevice. Remove the duplicated XInput2 function, and use an SDL_VideoData parameter for X11_FindWindow to avoid an unnecessary dereference.
The Emscripten support for setting window icons introduced in #14490 does not work when using pthreads. Using `SetWindowIcon` will cause the program to crash. The reason for that is that the `Blob` constructor does not accept shared memory (`SharedArrayBuffer`).
We need to create a local copy of the icon data if necessary.
* Implemented EnumerateStorageDirectory()
* Implemented RemoveStoragePath()
* Fixed init failure if the application previously crashed with a write batch in progress
* Allow creation of multiple Steam storage objects, the write batch is complete when the last storage is closed
* Check to see if a file exists in GetStoragePathInfo()
* GPU: D3D12: Missing WinPixEventRuntime.dll now logs warning at device creation time.
* GPU: D3D12: Debug label functions are now a no-op when WinPixEventRuntime.dll is missing.
* Docs: GPU: Debug function documentation now notes WinPixEventRuntime.dll is required under D3D12.
In the unlikely case that the overflow check should fail,
the else clause would switch to the truncated stack message
without updating the len variable. This would contain the
return value from vsnprintf(), meaning it could point beyond
the buffer.
The subsequent code which trims NL and CR from the buffer,
would then read -- and possibly write -- out-of-bounds.
To fix this, we split the two joint conditions into separate
if-clauses, and adjust the len variable in the case where we
know the message buffer was truncated.
This prevents validation errors on D3D12 caused by the previous solution
that utilized internal D3D12 functions. This is still the fallback
solution if WinPixEventRuntime.dll is not present in PATH, but a warning
is printed to let you know how to fix these errors.
At best, this is a no-op.
At worst, it might:
- Clobber a signal handler someone registered after us
- Overwrite the signal mask or flags
- Cause unregistration to fail (sigaction() isn't guaranteed to return the exact pointer passed to signal())
