mutexes Implement process Exclusive resources

Background: Develop a set of hardware-dependent software that allows only one software process to run in a single time to avoid hardware resource invocation conflicts.

Method: Use a mutex to determine if the software is started, and if so, to close the software that is about to start.

Code:

1 Static class Program2     {3         /// <summary>4         ///The main entry point for the application.5         /// </summary>6         StaticMutex _mutex;7 8 [STAThread]9         Static voidMain ()Ten         { One             BOOLfirstinstance; A_mutex =NewMutex (false,"DFS. Pos. Checkcashing", outfirstinstance); -             if(!firstinstance) -                 return; the  -              -         } -}
