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 |
); |
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.
