How to access the on the Steamworks Partner site ? SteamAPI WriteMiniDump

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

: This parameter corresponds to the exception code thrown by the system (e.g., EXCEPTION_ACCESS_VIOLATION ). It allows the developer to pass the specific error code that triggered the crash handling routine. If the function is called manually without a specific exception context, this value may be set to 0 or a custom identifier.

The WriteMiniDump function in the Steam API is a debugging tool that allows developers to generate a mini-dump file for a specific process. This file contains information about the process's memory, threads, and other relevant data, which can be used to diagnose and troubleshoot issues.

SteamAPI_WriteMiniDump is Valve's direct interface for capturing and uploading crash information to the Steam backend. Once crash reporting is properly implemented, Steam automatically uploads mini dumps after a configurable number of similar exceptions are thrown (default: 10). SteamAPI WriteMiniDump

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.

Be aware that minidumps can contain memory contents, which might include sensitive user information. Conclusion

If you’ve called SteamAPI_WriteMiniDump but can’t find the .dmp file on disk, double‑check:

: For stability, many developers use a separate "watchdog" or subprocess to handle the crash. This ensures that even if the main game process is frozen or out of memory, the crash handler can still write the dump and clean up resources—such as closing fullscreen windows or detaching from memory—before exiting. Why It Matters How to access the on the Steamworks Partner site

: The game registers a custom exception handler to "catch" unhandled errors before the operating system terminates the process.

For players, this function is the "invisible reporter." When a game crashes and sends a report, Valve’s backend aggregates these files. Developers can then visit their Steamworks Partner dashboard to see which crashes are affecting the most people.

When using WriteMiniDump , keep in mind:

After the dumps are uploaded, you can inspect every crash on the page inside the Steamworks Partner backend. Before the upload, minidumps are always saved locally in your game’s install directory, so you can examine them directly if needed. It allows the developer to pass the specific

SteamAPI_WriteMiniDump is a critical function provided by the Steamworks SDK that allows game developers to generate crash dumps (minidumps) when a game encounters an unhandled exception. These dumps, when combined with Valve's error reporting infrastructure, provide detailed call stacks, register values, and system information, significantly reducing time-to-fix for stability issues. This paper details the mechanism of WriteMiniDump , its implementation best practices, and the benefits of integrating it into the Steamworks pipeline. 1. Introduction

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