The OVERLAPPED structure contains information used in asynchronous input and output (I/O).
typedef struct _OVERLAPPED { // o DWORD Internal; DWORD InternalHigh; DWORD Offset; DWORD OffsetHigh; HANDLE hEvent; } OVERLAPPED;
You can use the HasOverlappedIoCompleted macro to determine whether an asynchronous I/O operation has completed. You can use the CancelIo function to cancel an asynchronous I/O operation.
CancelIo, ConnectNamedPipe, CreateFile, GetOverlappedResult, HasOverlappedIoCompleted, ReadFile, ReadFileEx, TransactNamedPipe, WriteFile, WriteFileEx
