Use Functions
The WNetAddConnection2, WNetCancelConnection2 WNetEnumResource, WNetGetConnection functions should be used instead of the NetUse functions, which are obsolete.
The use functions examine or control connections (uses) between workstations
and servers. They are:
NetUseAdd
NetUseDel
NetUseEnum
NetUseGetInfo
Connections are distinguished from sessions: a session is established the
first time a workstation makes a connection to a shared resource on the server; all
further connections between the workstation and the server are part of this
same session until the session ends. Two types of connections can be made:
device-name connections (which can only be explicit) and universal-naming convention
(UNC) connections (which can be explicit or implicit).
Connections are made on a per-user basis. A connection made by a user is
deleted when that user logs off. For this reason the NetUse functions are local
only, since a connection set up by a remote user would not be accessible to any
other users, even the user that was interactively logged onto that computer.
The NetUseAdd function creates a device-name connection or an explicit UNC connection.
Implicit UNC connections are made by the function responsible for the connection.
The NetUseAdd function establishes an explicit connection between the local computer and a
resource shared on a server by redirecting a local device name to the share
name of a remote server resource (\\<servername>\<sharename>). Once a device-name
connection is made, users or applications can use the remote resource by
specifying the local device name. To establish an implicit UNC connection, an
application passes the share name of a resource to any function that accepts UNC
paths. The function accepts the UNC name and makes a connection to the specified
share name. All further requests on this connection require the full share name.
The NetUseDel function ends a connection to a shared resource. The NetUseEnum function enumerates all current connections between the local computer and
resources on remote servers. The NetUseGetInfo function returns information about a connection to a shared resource.
The use functions are available at three information levels:
USE_INFO_0
USE_INFO_1
Information level 2 is not available if the function is remoted to a LAN
Manager 2.x system. In that case, ERROR_NOT_SUPPORTED will be returned.
USE_INFO_2
