// Initializing the Steamworks SDK
// -----------------------------
// 
// There are three different methods you can use to initialize the Steamworks SDK, depending on
// your project's environment. You should only use one method in your project.
// 
// If you are able to include this C++ header in your project, we recommend using the following
// initialization methods. They will ensure that all ISteam* interfaces defined in other
// C++ header files have versions that are supported by the user's Steam Client:
// - SteamAPI_InitEx() for new projects so you can show a detailed error message to the user
// - SteamAPI_Init() for existing projects that only display a generic error message
// 
// If you are unable to include this C++ header in your project and are dynamically loading
// Steamworks SDK methods from dll/so, you can use the following method:
// - SteamAPI_InitFlat()


// See "Initializing the Steamworks SDK" above for how to choose an init method.
// On success k_ESteamAPIInitResult_OK is returned. Otherwise, returns a value that can be used
// to create a localized error message for the user. If pOutErrMsg is non-NULL,
// it will receive an example error message, in English, that explains the reason for the failure.
//
// Example usage:
// 
//   SteamErrMsg errMsg;
//   if ( SteamAPI_Init(&errMsg) != k_ESteamAPIInitResult_OK )
//       FatalError( "Failed to init Steam.  %s", errMsg );
inline ESteamAPIInitResult SteamAPI_InitEx( SteamErrMsg *pOutErrMsg );

// supported by the user's client and is exported from the dll

//

//
// Returns false if no action needs to be taken. This means that your executable was started through
// the Steam client, or a steam_appid.txt file is present in your game's directory (for development).
// Your current process should continue if false is returned.
//

// since the DRM wrapper will ensure that your application was launched properly through Steam.
