| DWORD WNetCancelConnection(lpszName, fForce) | |||||
| LPTSTR lpszName; | /* pointer to resource name to disconnect | */ | |||
| BOOL fForce; | /* flag for forcing disconnect | */ | |||
The WNetCancelConnection function breaks an existing network connection.
lpszName
Points to a null-terminated string that specifies the name of either the redirected local device or the remote network resource to disconnect from. If lpszName specifies a redirected local device, only the specified redirection is broken, and a persistent connection will no longer be persistent. (That is, Windows will not restore the connection during subsequent log-on operations.) If lpszName specifies a remote network resource, all connections to the remote network resource are broken, and any persistent connections remain persistent.
fForce
Specifies whether the disconnection should occur even if there are open files or jobs on the connection. If fForce is FALSE, the function fails if there are open files or jobs.
If the function is successful, the return value is NO_ERROR. Otherwise, it is an error code, which may be one of the following:
| 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. Use the WNetGetLastError function to obtain a description of the error. |
| ERROR_NOT_CONNECTED | The name specified by lpszName is not a redirected device, or the system is not currently connected to lpszName. |
| ERROR_OPEN_FILES | There are open files and the fForce parameter was FALSE. |
This function returns error codes for compatibility with Windows 3.1. For compatibility with Win32, the function also sets the error-code value returned by the GetLastError function.
