|
|
* The async_compose function simplifies the implementation of composed
|
|
* asynchronous operations automatically wrapping a stateful function object
|
|
* with a conforming intermediate completion handler.
|
|
*
|
|
* @param implementation A function object that contains the implementation of
|
|
* the composed asynchronous operation. The first argument to the function
|
|
* object is a non-const reference to the enclosing intermediate completion
|
|
* handler. The remaining arguments are any arguments that originate from the
|
|
* completion handlers of any asynchronous operations performed by the
|
|
* implementation.
|
|
*
|
|
* @param token The completion token.
|
|
*
