SteamAPI_WriteMiniDump does not catch crashes on its own. You cannot just initialize Steam and expect it to work. You must wrap your game loop in Structured Exception Handling (SEH) code using __try and __except .
extern "C" S_API void S_CALLTYPE SteamAPI_WriteMiniDump( uint32 uUnsignedStructuredExceptionCode, void* pExceptionInfo, uint32 uBuildId ); Use code with caution.
The function signature in the Steamworks SDK headers looks like this: SteamAPI WriteMiniDump
A minidump is a compact file containing a snapshot of a process's state at the exact moment of a crash. Unlike a full memory dump, which can be gigabytes in size, a minidump typically ranges from a few kilobytes to a few megabytes. It contains essential debugging data, including:
