FltCreateFileEx可能會傳回STATUS_FILE_LOCK_CONFLICT做為傳回值,或在 IoStatusBlock 參數所指向之IO_STATUS_BLOCK結構的Status成員中傳回。 只有在NTFS記錄檔已滿,且 FltCreateFileEx嘗試處理這種情況時,才會發生此錯誤。 備註 文件系統迷你篩選驅動程式應該呼叫FltCreateFileEx,而不是FltCreateFile,以取得檔案物件指標...
如果 FltCreateFileEx 的原始呼叫端未指定FILE_SHARE_READ、FILE_SHARE_WRITE或FILE_SHARE_DELETE,則無法對檔案執行其他開啟作業,因為原始呼叫端具有檔案的獨佔存取權。若要成功開啟共用檔案,要求的 DesiredAccess 與檔案的 DesiredAccess 和所有先前尚未透過 FltClose 發行的 ShareAccess 規格相容。 也就是說,為指定...
因此,从对FltCreateFileEx2的调用返回后,ECP 列表应保持不变,并可能传递给FltCreateFileEx2的其他调用以执行其他创建操作。 请注意,操作系统不会自动解除分配 ECP 列表结构 -FltCreateFileEx2的调用方必须通过调用FltFreeExtraCreateParameterList例程解除分配此结构。 若要在事务上下文中创建/打开文件,请将 IO_DRIVER_...

The CreateOptions FILE_OPEN_REQUIRING_OPLOCK flag eliminates the time between when you open the file and request an oplock that could potentially enable a third party to open the file and get a sharing violation. An application can use the FILE_OPEN_REQUIRING_OPLOCK flag on FltCreateFile...

FltCreateFileEx2might return STATUS_FILE_LOCK_CONFLICT as the return value or in theStatusmember of the IO_STATUS_BLOCK structure that is pointed to by the IoStatusBlock parameter. This would occur only if the NTFS log file is full, and an error occurs whileFltCreateFileEx2tries to handle...
Hi, I have a very disturbing problem in my minifitler. I find out that FltGetFileNameInformation May generate a call to IoCreateFileEx which is again recieved by my minifilter. I am passing FltGetFileNameInformation …
CreateDisposition 值FILE_SUPERSEDE要求呼叫端具有現有檔案物件的 DELETE 存取權。 如果是的話,在現有檔案上成功呼叫 FltCreateFileEx2 並FILE_SUPERSEDE會有效地刪除該檔案,然後重新建立該檔案。 這表示,如果檔案已經由另一個線程開啟,它會指定 shareAccess參數並設定FILE_SHARE_DELETE旗標來開啟檔案。 請注意,這種...
