Operating Systems Supported

Points to a null-terminated string that specifies the name of either the redirected local device or the remote network resource to disconnect from. When this parameter specifies a redirected local device, only the specified device redirection is broken. If the parameter specifies a remote network resource, only the connections to remote networks without devices are broken.
Specifies whether the disconnection is to occur even if there are open files or jobs on the connection. If this parameter is FALSE, the function fails if there are open files or jobs.
If the function succeeds, the return value is NO_ERROR.
If the function fails, the return value is an error code. To get extended error information, call GetLastError. GetLastError may return one of the following error codes:
The user profile is in an incorrect format.
The system is unable to open the user profile to process persistent connections.
The device is in use by an active process and cannot be disconnected.
A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
The name specified by the lpName parameter is not a redirected device, or the system is not currently connected to the device specified by the parameter.
There are open files, and the fForce parameter is FALSE.
