Mükemmel soru! 7 yıl gecikti, ama işte bir cevap, ya da daha önemlisi, onu nasıl bulabilirim. Yani, ReadDirectoryChangesW için belgeleri: Parametreler bölümünde
https://msdn.microsoft.com/en-us/library/windows/desktop/aa365465%28v=vs.85%29.aspx
FileIOCompletionRoutine bir bağlantı veriyor: Örnekler bölümünde Tamamlama rutinleri kullanarak adlandırılmış yöneltme sunucusuna bir bağlantı verilir
https://msdn.microsoft.com/en-us/library/windows/desktop/aa364052%28v=vs.85%29.aspx
:
( ) (ReadFileEx Bu iki işlevleri kullanarak bunlardan bir örnek görebilirsiniz
https://msdn.microsoft.com/en-us/library/windows/desktop/aa365468%28v=vs.85%29.aspx
ve: inanın
veya hatta ReadDirectoryChangesW kullanmak ama aslında da FileIOCompletionRoutine kullanan ReadFileEx kullanılarak bir örnek verir vermez ve bu kod parçasında) (uygulama tanımlı geri çağırma işlevi FileIOCompletionRoutine bir uygulamasıdır) CompletedReadRoutine:
// CompletedWriteRoutine(DWORD, DWORD, LPOVERLAPPED)
// This routine is called as a completion routine after writing to
// the pipe, or when a new client has connected to a pipe instance.
// It starts another read operation.
VOID WINAPI CompletedWriteRoutine(DWORD dwErr, DWORD cbWritten,
LPOVERLAPPED lpOverLap)
{
LPPIPEINST lpPipeInst;
BOOL fRead = FALSE;
// lpOverlap points to storage for this instance.
lpPipeInst = (LPPIPEINST) lpOverLap;
// The write operation has finished, so read the next request (if
// there is no error).
if ((dwErr == 0) && (cbWritten == lpPipeInst->cbToWrite))
fRead = ReadFileEx(
lpPipeInst->hPipeInst,
lpPipeInst->chRequest,
BUFSIZE*sizeof(TCHAR),
(LPOVERLAPPED) lpPipeInst,
(LPOVERLAPPED_COMPLETION_ROUTINE) CompletedReadRoutine);
// Disconnect if an error occurred.
if (! fRead)
DisconnectAndClose(lpPipeInst);
}
// CompletedReadRoutine(DWORD, DWORD, LPOVERLAPPED)
// This routine is called as an I/O completion routine after reading
// a request from the client. It gets data and writes it to the pipe.
VOID WINAPI CompletedReadRoutine(DWORD dwErr, DWORD cbBytesRead,
LPOVERLAPPED lpOverLap)
{
LPPIPEINST lpPipeInst;
BOOL fWrite = FALSE;
// lpOverlap points to storage for this instance.
lpPipeInst = (LPPIPEINST) lpOverLap;
// The read operation has finished, so write a response (if no
// error occurred).
if ((dwErr == 0) && (cbBytesRead != 0))
{
GetAnswerToRequest(lpPipeInst);
fWrite = WriteFileEx(
lpPipeInst->hPipeInst,
lpPipeInst->chReply,
lpPipeInst->cbToWrite,
(LPOVERLAPPED) lpPipeInst,
(LPOVERLAPPED_COMPLETION_ROUTINE) CompletedWriteRoutine);
}
// Disconnect if an error occurred.
if (! fWrite)
DisconnectAndClose(lpPipeInst);
}
Bu büyük bir cevap değil (sadece olmadığını keşfetmek oldu Hatta bu işlevleri kullanmak istedim), ama insanların işe başlamasına yardımcı olmalı.
