S_API void S_CALLTYPE SteamAPI_WriteMiniDump( uint32 uStructuredExceptionCode, void* pvExceptionInfo, uint32 uBuildID ); Use code with caution. Argument Breakdown

Testing a crash handler can be tricky—after all, you can’t afford to ship code that crashes on purpose. Here’s a safe testing regimen:

// This try block allows the SE translator to intercept all exceptions. return RealMain( hInstance, lpCmdLine, nCmdShow );

What are you using? (C++, Unity, Unreal Engine?) Do you need an automated way to upload dumps to a server ? Are you targeting Linux / Steam Deck users as well? SteamAPI WriteMiniDump

Always call SteamAPI_SetMiniDumpComment immediately before writing the dump to provide context like the current game level or free memory.

For the whole _set_se_translator pattern to work, you enable SEH in your compiler settings. On Visual Studio, that means using /EHa (Enable C++ EH with SEH exceptions) or /EHs with additional flags. If your compiler flags are wrong, exceptions may bypass your translator entirely.

It captures debugging data from the calling process and any active game threads. Technical Signature and Parameters return RealMain( hInstance, lpCmdLine, nCmdShow ); What are

Drag and drop the .dmp file directly into Visual Studio.

S_API void S_CALLTYPE SteamAPI_WriteMiniDump( uint32 uStructuredExceptionCode, void* pvExceptionInfo, uint32 uBuildID ); Use code with caution.

return RealMain(hInstance, lpCmdLine, nCmdShow); uint32 uBuildID )

Adding a specific comment can transform a minidump from a stack trace into a powerful clue, providing context that can help replicate a difficult-to-track bug.

The moment the crash hit, his tool caught the SteamAPI call red-handed.
