void MiniDumpFunction( unsigned int nExceptionCode, EXCEPTION_POINTERS *pException )

If you must rely on Steam’s built‑in system for a legacy 32‑bit Windows title, SteamAPI_WriteMiniDump still works as documented—just don’t expect new features or fixes.

I will now write the article. Understanding SteamAPI_WriteMiniDump: The Complete Guide to Steam Error Reporting SteamAPI WriteMiniDump

Visual Studio will attempt to map the dump to your source code.

#include "steam/steam_api.h" #include // Example Exception Filter long __stdcall MyExceptionFilter(EXCEPTION_POINTERS* pExceptionInfo) // 1. Define where to save the dump const char* pchFileName = "crash_dump.dmp"; // 2. Call SteamAPI_WriteMiniDump // The second parameter is optional user comment, third is the exception info SteamAPI_WriteMiniDump(0, nullptr, 0); // Optional: Log to a file that a dump was written // ... return EXCEPTION_EXECUTE_HANDLER; int main() // Initialize Steam if (!SteamAPI_Init()) return -1; // Set the exception filter SetUnhandledExceptionFilter(MyExceptionFilter); // ... Game Loop ... SteamAPI_Shutdown(); return 0; Use code with caution. Advanced Options

From a developer’s perspective, SteamAPI_WriteMiniDump is called only when an unhandled exception occurs—typically an access violation (segfault), stack overflow, or illegal instruction. The call happens inside the game’s crash handler. Common root causes include: #include "steam/steam_api

// Initialize Steamworks if (!SteamAPI_Init())

The specific needed for SEH to work in Visual Studio?

SteamAPI WriteMiniDump

While Windows provides native APIs such as MiniDumpWriteDump via DbgHelp.dll , integrating crash reporting with a specific distribution platform requires handling build IDs, versioning, and file transmission manually. The Steamworks API function SteamAPI_WriteMiniDump serves as a wrapper around these native capabilities, tightly coupling the crash dump generation with the Steam client’s backend infrastructure.

SteamAPI_WriteMiniDump is the key piece of Steam’s Error Reporting feature. When you implement error reporting correctly, Steam will automatically upload minidumps—but not after every single crash. Instead, it waits until have been thrown before uploading the dumps. This throttling prevents flooding the server with duplicate reports.
