#define GMP_API_ASYNC_SHUTDOWN "async-shutdown"

// API exposed by the plugin library to manage asynchronous shutdown.
// Some plugins require special cleanup which may need to make calls
// to host services and wait for async responses.
//
// To enable a plugins to block shutdown until its async shutdown is
// complete, implement the GMPAsyncShutdown interface and return it when
// your plugin's GMPGetAPI function is called with "async-shutdown".
// When your GMPAsyncShutdown's BeginShutdown() implementation is called
// by the GMP host, you should initate your async shutdown process.
// Once you have completed shutdown, call the ShutdownComplete() function
// of the GMPAsyncShutdownHost that is passed as the host argument to the
// GMPGetAPI() call.
//
// Note: Your GMP's GMPShutdown function will still be called after your
// call to ShutdownComplete().
//
// API name macro: GMP_API_ASYNC_SHUTDOWN
// Host API: GMPAsyncShutdownHost
