The MSFT_SmbOpenFile class has these types of members:

Methods

The MSFT_SmbOpenFile class has these methods.

Method Description
ForceClose Forcibly closes a file that is open on behalf of an SMB client. Unsaved data might be lost.

Properties

The MSFT_SmbOpenFile class has these properties.

ClientComputerName

Data type: string

Access type: Read-only

The name of the computer from which the file handle was opened.

ClientUserName

Data type: string

Access type: Read-only

The name of the user that opened the file handle.

ClusterNodeName

Data type: string

Access type: Read-only

Name of the computer that is actually serving this handle. This is meaningful when the server is part of a cluster and the scope of the session might be served by several servers in the cluster.

ContinuouslyAvailable

Data type: boolean

Access type: Read-only

Indicates whether this handle supports continuous availability. Continuously available handles will survive server failovers without any interruption to the client application.

Encrypted

Data type: boolean

Access type: Read-only

Indicates whether the SMB connection is encrypted. For more information, see SMB Encryption.

FileId

Data type: uint64

Access type: Read-only

Qualifiers: key

An identifier that uniquely identifies the open file handle.

Locks

Data type: uint32

Access type: Read-only

Number of locks held on this handle.

Path

Data type: string

Access type: Read-only

Specified the server-local path to the opened file.

Permissions

Data type: uint32

Access type: Read-only

The access mask for this handle.

ScopeName

Data type: string

Access type: Read-only

Scope name of this handle. It can be * (meaning no scope) or a file server resource name (if the server is part of a cluster). ScopeName should match the scope name of the associated session.

SessionId

Data type: uint64

Access type: Read-only

An identifier that identifies the session in which this file handle was opened.

ShareRelativePath

Data type: string

Access type: Read-only

Specifies the share-relative path to the opened file.

Signed

Data type: boolean

Access type: Read-only

Indicates whether the SMB connection is encrypted. If the SMB connection is encrypted (the Encrypted property is True) then the Signed property will be set to False, even though an encrypted connection is also signed. For more information, see Require SMB Security Signatures.
