WNetCancelConnection  12AYGDC 

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 WNetCancelConnection26G16Y. 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 GetLastError11C2VS7. 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 WNetGetLastError1KVEZQM 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 GetLastError11C2VS7.
