Canceling a Network Connection
To cancel a connection to a network resource, an application can call the WNetCancelConnection2 function, as shown in the following example.
The call to WNetCancelConnection2 specifies that a network connection should no longer be persistent. The sample calls an application-defined error handler to process errors, and the TextOut function for printing.
DWORD dwResult; // Call the WNetCancelConnection2 function, specifying // that the connection should no longer be a persistent one. // dwResult = WNetCancelConnection2("z:", CONNECT_UPDATE_PROFILE, // remove connection from profile FALSE); // fail if open files or jobs // Process errors. // The device is not a local redirected device. // if (dwResult == ERROR_NOT_CONNECTED) { printf("Drive z: not connected.\n"); return dwResult; } // Call an application-defined error handler. // else if(dwResult != NO_ERROR) { printf("WNetCancelConnection2 failed.\n"); return dwResult; } // // Otherwise, report canceling the connection. // printf("Connection closed for z: drive.\n");
The WNetCancelConnection function is supported for compatibility with earlier versions of Windows for Workgroups. For new applications, use WNetCancelConnection2.
