SteamAPI RestartAppIfNecessary function explained
How it works and what it does
The SteamAPI RestartAppIfNecessary function is one of the first functions that you need to call in your game code if you want to use the Steamworks API. This function checks if your executable was launched through Steam and relaunches it through Steam if it wasn't. This is optional but highly recommended as the Steam context associated with your application (including your App ID) will not be set up if the user launches the executable directly.
The function takes one parameter, which is your App ID. This is a unique identifier that Steam assigns to your game when you register it on the Steamworks website. You can find your App ID on your App Admin page or in the steam_appid.txt file that is included in the Steamworks SDK. The function returns a boolean value that indicates whether your game needs to be restarted or not. If it returns true, you should exit your game immediately as Steam will relaunch it for you. If it returns false, you can continue with your game initialization as normal.
When and why you should use it
You should use the SteamAPI RestartAppIfNecessary function at the very beginning of your game code, before any other calls to the Steamworks API or any other initialization code. This will ensure that your game has the correct App ID and that all the Steam features and solutions are available for your game.
There are several reasons why you should use this function. First, it makes sure that your game is always launched through Steam, which means that your players will have access to their Steam account, friends list, achievements, cloud saves, etc. Second, it allows you to use Valve Anti-Cheat (VAC) functionality and DRM protection for your game, which can prevent cheating and piracy. Third, it enables you to use some advanced features of the Steamworks API, such as overlay notifications, rich presence, remote storage, etc.
Steam Apidll file explained
What it is and what it does
The steam_api.dll file is a dynamic link library (DLL) file that contains the implementation of the Steamworks API functions. It is used by your game executable to communicate with the Steam client and access the Steamworks features. The steam_api.dll file is provided by the Steamworks SDK and you need to include it in your game folder along with your executable and the steam_appid.txt file.
How to install and update it
To install the steam_api.dll file, you need to download the Steamworks SDK from the Steamworks website. The SDK contains various tools, libraries, and documentation for using the Steamworks API in your game development.

You can also use the Steamworks Data API to access raw data and create custom reports and dashboards. - Quality: You can improve the quality and stability of your game by using the Steamworks API features and solutions, such as anti-cheat, DRM, crash reporting, debugging, testing, etc. You can also get feedback and suggestions from your players and other developers through the Steamworks Developer Forums and the Steamworks Developer Support. - Innovation: You can enhance the gameplay and user experience of your game by using the Steamworks API features and solutions, such as achievements, leaderboards, multiplayer, matchmaking, networking, cloud storage, workshop, overlay, etc. You can also integrate your game with other Steam features and products, such as SteamVR, Steam Controller, Steam Link, Steam Remote Play, etc. How to get started with Steamworks SDK and documentation
To get started with the Steamworks API in your game development, you need to download and install the Steamworks SDK from the Steamworks website. The SDK contains various tools, libraries, and documentation for using the Steamworks API in your game development. You need to register as a Steamworks developer and sign a non-disclosure agreement (NDA) to access the SDK.
Once you have downloaded and installed the SDK, you need to read the documentation that is included in the SDK folder. The documentation contains detailed information about each sub-API of the Steamworks API, including its functions, parameters, return values, errors, callbacks, etc. The documentation also contains code examples and best practices for using the Steamworks API in your game code.
You can also access the online version of the documentation on the Steamworks website. The online documentation is updated regularly with new features and changes. You can also use the search function to find specific topics or keywords in the documentation.
How to access Steamworks features and solutions in your game code
To access the Steamworks features and solutions in your game code, you need to follow these steps:
- Include the header files: You need to include the header files that correspond to the sub-APIs that you want to use in your game code. For example, if you want to use the user authentication sub-API, you need to include the steam_api.h header file. If you want to use the achievements sub-API, you need to include the isteamuserstats.h header file. You can find all the header files in the public folder of the SDK. - Initialize the Steamworks API: You need to initialize the Steamworks API before calling any other functions. To do this, you need to call the SteamAPI_Init function at the beginning of your game code. This function will return true if it succeeds or false if it fails. You should check for errors and handle them accordingly. - Get an interface pointer: You need to get an interface pointer for each sub-API that you want to use in your game code. An interface pointer is a variable that points to an object that implements all the functions of a sub-API. To get an interface pointer, you need to call one of the global accessor functions that are defined in the steam_api.h header file. For example, if you want to get an interface pointer for the user authentication sub-API, you need to call the SteamUser function. This function will return a pointer to an ISteamUser object that you can use to call the user authentication functions. - Call the functions: You can now call the functions of the sub-APIs that you want to use in your game code using the interface pointers that you have obtained. For example, if you want to get the Steam ID of the current user, you can call the GetSteamID function of the ISteamUser object. This function will return a CSteamID object that contains the Steam ID of the user. You can use this object to perform various operations on the user, such as checking their online status, sending them messages, inviting them to games, etc. - Handle the callbacks: Some of the functions of the Steamworks API are asynchronous, which means that they do not return a value immediately but instead trigger a callback when they are completed. A callback is a function that is executed when a certain event occurs, such as a user logging in, an achievement being unlocked, a leaderboard being updated, etc. To handle the callbacks, you need to create a class that inherits from one of the callback base classes that are defined in the steam_api.h header file. For example, if you want to handle the callbacks for the user authentication sub-API, you need to create a class that inherits from CSteamAPIContext. Then, you need to override the virtual functions that correspond to the callbacks that you want to handle. For example, if you want to handle the callback for when a user logs in or out, you need to override the OnUserLogOnResponse function. This function will receive a UserLogOnResponse_t object that contains information about the user logon status. You can use this object to perform various actions based on the logon result, such as displaying a message, updating the UI, etc. - Run callbacks: You need to run callbacks regularly in your game loop to ensure that your game receives and handles all the events that occur from the Steamworks API. To do this, you need to call one of the global run callbacks functions that are defined in the steam_api.h header file. For example, if you want to run callbacks for the user authentication sub-API, you need to call the SteamAPI_RunCallbacks function. This function will execute all the callbacks that are registered for the user authentication sub-API. You should call this function at least once per frame in your game loop. Conclusion
