A berth is a designated location in a port or harbour used for mooring vessels when they are not at sea. Berths provide a vertical front which allows safe and secure mooring that can then facilitate the unloading or loading of cargo or people from vessels. 1 Locations in a Port.
Asynchronous Callbacks. Delegates can also be used as CallBacks. CallBacks are used in many Windows API calls. You pass in a function pointer to the API call. When the API call gets finished with it's job, it then âcalls backâ to the function via the function pointer you passed it. This allows your code to know when the API call is done.
Asynchronous Procedure Calls. An asynchronous procedure call (APC) is a function that executes asynchronously in the context of a particular thread. When an APC is queued to a thread, the system issues a software interrupt. The next time the thread is scheduled, it will run the APC function.n APC generated by the system is called a kernel-mode APC. An APC generated by an application is called a user-mode APC. A thread must be in an alertable state to run a user-mode APC. Each thread has its own APC queue.
