: Note that Steam Error Reporting (the automatic submission system) is nearing its End-Of-Lifetime. While SteamAPI_WriteMiniDump is still useful for generating local files you can request from users, automated backend collection is limited.
A typical implementation involves setting up an unhandled exception filter:
SteamAPI_SetMiniDumpComment( "Error occurred during asset streaming on loading screen." ); Use code with caution.
When a Steam-integrated game crashes, it invokes SteamAPI_WriteMiniDump (or a similarly named internal function) to log the crash data. The error message itself is not the cause of the crash; it is the symptom and the log mechanism . However, users often see this text in an error dialog or in the Windows Event Viewer.
As highlighted in official Steamworks Features documentation, the legacy Steam Error Reporting subsystem is nearing its End-Of-Lifetime (EOL) status. Valve provides limited technical support for this tool for newer titles. SteamAPI WriteMiniDump
: It is typically used within a custom exception handler (via Win32 _set_se_translator ) to notify Steam of an impending crash. Developer Review: Pros & Cons Seamless Integration
SteamAPI_WriteMiniDump is a function within the Steamworks API
When SteamAPI_WriteMiniDump executes, it automatically saves the .dmp file inside the game's working directory or the directory containing the game executable.
For game developers, a crash in the wild is a nightmare. Without proper data, reproducing a user's crash—caused by a specific combination of hardware, software, and in-game actions—is almost impossible. This is where SteamAPI_WriteMiniDump comes into play. : Note that Steam Error Reporting (the automatic
If you are :
The specific Windows Structured Exception Handling (SEH) code (e.g., 0xC0000005 for an Access Violation / null pointer dereference).
Three dots appeared. Then:
The official Rust bindings define the function as: understand these official constraints:
The string is often seen in crash logs , console outputs , or error reports generated by games or applications using the Steamworks SDK.
The underlying architecture of SteamAPI_WriteMiniDump and its companion features are explicitly supported on 32-bit Windows applications .
This is the most common source of confusion. The function . On 64‑bit Windows, Linux (including Steam Deck), or macOS, it’s a no‑op. This is stated clearly in the documentation: “ only available for Windows 32‑bit applications ”.
Before implementing, understand these official constraints:
