///

// Helpers for asynchronously executing a base::Closure (bound function or

// method) on a CEF thread. Creation of base::Closures can be facilitated using

// base::Bind. See include/base/cef_callback.h for complete usage instructions.

//

// TO use these helpers you should include this header and the header that

// defines base::Bind.

//

// #include "include/base/cef_bind.h"

// #include "include/wrapper/cef_closure_task.h"

//

// Example of executing a bound function:

//

// // Define a function.

// void MyFunc(int arg) { /* do something with |arg| on the UI thread */ }

//

// // Post a task that will execute MyFunc on the UI thread and pass an |arg|

// // value of 5.

// CefPostTask(TID_UI, base::Bind(&MyFunc, 5));

//

// Example of executing a bound method:

//

// // Define a class.

// class MyClass : public CefBaseRefCounted {

// public:

// MyClass() {}

// void MyMethod(int arg) { /* do something with |arg| on the UI thread */ }

// private:

// IMPLEMENT_REFCOUNTING(MyClass);

// };

//

// // Create an instance of MyClass.

// CefRefPtr<MyClass> instance = new MyClass();

//

// // Post a task that will execute MyClass::MyMethod on the UI thread and pass

// // an |arg| value of 5. |instance| will be kept alive until after the task

// // completes.

// CefPostTask(TID_UI, base::Bind(&MyClass::MyMethod, instance, 5));

///

///

// Create a CefTask that wraps a base::Closure. Can be used in combination with

// CefTaskRunner.

///

CefRefPtr<CefTask> CefCreateClosureTask(const base::Closure& closure);

///

// Post a Closure for execution on the specified thread.

///

bool CefPostTask(CefThreadId threadId, const base::Closure& closure);

///

// Post a Closure for delayed execution on the specified thread.

///

bool CefPostDelayedTask(CefThreadId threadId,

const base::Closure& closure,
