WNetCancelConnection    
The WNetCancelConnection
function breaks an existing network connection. 
The function
is provided for compatibility with earlier versions of Microsoft Windows. For
new applications, use the WNetCancelConnection2 function. 
DWORD WNetCancelConnection(
|     LPTSTR lpName, | // pointer to
  resource name to be disconnected  | 
|     BOOL fForce  | // flag for
  unconditional disconnect  | 
|    ); |  | 
Parameters
lpName
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. 
fForce
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. 
Return Values
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: 
| Value | Meaning | 
| ERROR_BAD_PROFILE | The user
  profile is in an incorrect format. | 
| ERROR_CANNOT_OPEN_PROFILE | The system
  is unable to open the user profile to process persistent connections. | 
| ERROR_DEVICE_IN_USE | The device
  is in use by an active process and cannot be disconnected. | 
| ERROR_EXTENDED_ERROR | A
  network-specific error occurred. To get a description of the error, use the WNetGetLastError function. | 
| ERROR_NOT_CONNECTED | 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. | 
| ERROR_OPEN_FILES | There are
  open files, and the fForce parameter is FALSE. | 
The function
returns error codes for compatibility with Windows version 3.1. For
compatibility with the Win32 API, the function also sets the error code value
returned by GetLastError.
