The ShareAccess parameter determines whether separate threads can access the same file, possibly simultaneously. Provided that both callers have the appropriate access privileges, the file can be successfully opened and shared.

To successfully open a shared file, the DesiredAccess flags must be compatible with the DesiredAccess and ShareAccess flags of all the previous open operations that have not yet been released through.

That is, the DesiredAccess specified to NtCreateFile for a given file must not conflict with the accesses that other openers of the file have disallowed. If NtCreateFile is called with a existing file and either of these CreateDisposition values, the file will be replaced.

Overwriting a file is semantically equivalent to a supersede operation, except for the following:. When a directory file is created, the file system creates an appropriate structure on the disk to represent an empty directory for that particular file system's on-disk structure. If this option was specified and the given file to be opened is not a directory file, or if the caller specified an inconsistent CreateOptions or CreateDisposition value, the call to NtCreateFile will fail.

Specifying this flag places the following restrictions on the caller's parameters to other Zw Xxx File routines. This ensures that an oplock owner will be notified of any subsequent open request that causes a sharing violation.

This restriction no longer exists starting with Windows 8. The existing oplock will not be broken by this create operation. Similarly, if this call succeeds but the subsequent oplock request fails, an application that uses this flag must close its handle after it detects that the oplock request has failed.

To use it, you must complete the following steps:. Step 3 makes this practical only for Filter oplocks. This number is assigned by and specific to the particular file system. Because the filename field will partly contain a binary blob, it is incorrect to assume that this is a valid Unicode string, and more importantly may not be a null terminated string.

If the call to this function occurs in user mode, you should use the name " NtCreateFile " instead of " ZwCreateFile ". For calls from kernel-mode drivers, the Nt Xxx and Zw Xxx versions of a Windows Native System Services routine can behave differently in the way that they handle and interpret input parameters.
