handler_ptr::invoke

Invoke the handler in the owned object.

Synopsis
template<
    class... Args>
void
invoke(
    Args&&... args);
Description

This function invokes the handler in the owned object with a forwarded argument list. Before the invocation, the owned object is destroyed, satisfying the deallocation-before-invocation Asio guarantee. All instances of handler_ptr which refer to the same owned object will be reset, including this instance.

Remarks

Care must be taken when the arguments are themselves stored in the owned object. Such arguments must first be moved to the stack or elsewhere, and then passed, or else undefined behavior will result.
