Steamapi Writeminidump [top] Jun 2026

If you're debugging a crash in a Steam game and see a .dmp file next to the executable, it likely came from WriteMiniDump . You can open it with WinDbg or Visual Studio if you have matching symbols.

S_API void S_CALLTYPE SteamAPI_WriteMiniDump( uint32 uStructuredExceptionCode, void* pvExceptionInfo, uint32 uBuildID );

Understanding the Steamworks Crash Reporting System The Steamworks SDK provides PC game developers with robust tools to track, capture, and debug application crashes directly through the Steam infrastructure. At the core of this crash-reporting ecosystem is SteamAPI_WriteMiniDump , a specialized function designed to generate Windows minidump ( .mdmp ) files when a fatal error or unhandled exception occurs. SteamAPI WriteMiniDump

Once error reporting is implemented, crash data becomes visible in the Steamworks Partner backend. Navigate to the Error Reports page ( https://partner.steamgames.com/errors ) to view details for each crash, including frequency, stack traces, and any comments you embedded.

When using the WriteMiniDump function, developers should follow these best practices:

: A pointer to the actual technical details of the exception.

When called, WriteMiniDump generates a MiniDump for the specified process and writes it to the designated file. The resulting MiniDump can then be analyzed using tools like WinDbg or Visual Studio to diagnose issues and understand the state of the process at the time of the crash. If you're debugging a crash in a Steam game and see a

Once a MiniDump has been generated, it can be analyzed using tools like WinDbg or Visual Studio. These tools allow developers to:

Don't rely on users to email files. Create a system that prompts users to send the crash dump, or automatically uploads it to a backend service when the game restarts.

#include #include // 1. Define the unhandled exception filter LONG WINAPI OurCrashHandler(EXCEPTION_POINTERS* pExceptionInfo) // Retrieve your game's current build ID from Steam uint32 currentBuildId = SteamApps() ? SteamApps()->GetAppBuildId() : 0; // Get the specific exception code uint32 exceptionCode = pExceptionInfo->ExceptionRecord->ExceptionCode; // 2. Write the minidump using the Steam API SteamAPI_WriteMiniDump(exceptionCode, pExceptionInfo, currentBuildId); // Terminate the app cleanly after dumping data return EXCEPTION_EXECUTE_HANDLER; int main() // Initialize Steamworks if (!SteamAPI_Init()) return -1; // 3. Register the handler with the operating system SetUnhandledExceptionFilter(OurCrashHandler); // Game loop runs here... SteamAPI_Shutdown(); return 0; Use code with caution. Where Do the Dump Files Go?

// Close the file handle CloseHandle(hFile); And then he saw it

In the world of high-stakes PC gaming, a crash isn't just a technical glitch—it's a potential "Negative Review" on Steam. To prevent these catastrophic player experiences from becoming permanent bugs, Valve provides developers with a specialized tool: SteamAPI_WriteMiniDump . This function serves as the primary mechanism for Steam Error Reporting

Because of these limitations, consider this system as a supplement to other crash reporting solutions, not a comprehensive replacement.

, developers don't have to ask players for log files; Steam handles the heavy lifting of collection and categorization. How the Magic Happens: Implementation

The Steam API, developed by Valve Corporation, is a set of application programming interfaces (APIs) that allow game developers to interact with the Steam platform. One of the lesser-known functions within the Steam API is WriteMiniDump , a powerful tool that can be used to generate crash dumps for debugging purposes. In this article, we will explore the SteamAPI WriteMiniDump function, its uses, and how it can be leveraged to improve game development and debugging.

, allowing games to capture a "snapshot" of a crash and beam it directly to the developer's dashboard. What is a Mini-dump?

When using these bindings, call SteamAPI_WriteMiniDump from within an appropriate exception handler context. The function is marked unsafe because it operates with raw pointers and interacts directly with the Steam client.
