The I/O Manager sends the IRP_MJ_CREATE request when a new file or directory is being created, or when an existing file, device, directory, or volume is being opened. Normally this IRP is sent on behalf of a user-mode application that has called a Microsoft Win32 function such as CreateFile or on behalf of a kernel-mode component that has called IoCreateFile, IoCreateFileSpecifyDeviceObjectHint, ZwCreateFile, or ZwOpenFile. If the create request is completed successfully, the application or kernel-mode component receives a handle to the file object.

 

IRP_MJ_CREATE

发送时机:

IO管理器在一个文件或目录创建时,

或一个已存在的文件，设备，目录，Volume被打开时

发送此IRP.

通常在应用层调用CreateFile,或内核层调用:

IoCreateFile

IoCreateFileSpecifyDeviceObjectHint

ZwCreateFile

ZwOpenFile

引发此IRP的发送.

若创建成功，则应用层或内核组件会收到一个此文件对象的句柄.
