This guide will cover certain ways to detect restart or shutdown of the PC, as well as other similar events, such as log off or sleep.
Our function analyzes input parameter data, decides which event has occurred and executes certain code as a response to this event.
In order to catch shutdown event in a console application, we should start by creating our own handler function:
BOOL WINAPI HandlerRoutine(_In_ DWORD dwCtrlType);
Next, register it as a handler for this console application by using the following API function:
BOOL WINAPI SetConsoleCtrlHandler(_In_opt_ PHANDLER_ROUTINE HandlerRoutine, _In_ BOOL Add);
Creating IOCP and associating it with the file handles is done via the CreateloCompletionPort API function:
HANDLEWINAPICreateIoCompletionPort(_In_ HANDLE FileHandle,_In_opt_ HANDLE ExistingCompletionPort,_In_ ULONG_PTR CompletionKey,_In_ DWORD NumberOfConcurrentThreads);
Handle from the FileHandle parameter is associated with a new or existing completion port.
When the asynchronous I/O request for the IOCP-related file is completed, I/O manager creates an I/O completion packet and places it in the queue.
Packets are extracted from the queue when a worker thread calls the GetQueuedCompletionStatus API function:
BOOLWINAPIGetQueuedCompletionStatus(_In_ HANDLE CompletionPort,_Out_ LPDWORD lpNumberOfBytesTransferred,_Out_ PULONG_PTR lpCompletionKey,_Out_ LPOVERLAPPED * lpOverlapped,_In_ DWORD dwMilliseconds);
Here's a guide to understanding everything about API development and its importance in business transformation.The realm of API is extensive and is constantly expanding at a rapid pace.
The term API (Application Programming Interface) has been ruling the roots and it is playing a bigger role in the economy than ever before.APIs drive the modern world and we find them everywhere.
Moreover, we’ll also look at the must-have features in API development and the factors that affect its development process.Did you know as compared to 2019, 61% of the developers used APIs more in 2020?What is App Programming Interface (API)?App Programming Interface (API) is intermediary software that allows the applications to interact with each other.
The API can be a database system, web-based system, etc.
One of API’s better USPs is that mobile app developers don’t need to begin everything from scratch if they build for the same platform.
APIs can be used to show the data that is stored in another platform of the website.APIs are immensely powerful as they allow developers to build their product on someone else’s work.
