Example: Shared Memory Communication

The package includes the following examples:

• SharedMemoryExampleExt.project

  The project uses shared memory to read and write data with the SysShm library. The DataExchange structure is used for data exchange. Values from the shared memory are read to the deInstRead variable. The deInstWrite variable is used for writing values to shared memory. The values of deInstWrite are changed in each cycle.

  The values of both variables are displayed in the visualization.

The following examples read the value of the deInstWrite variable and write to the deInstRead variable:

• SharedMemoryCLinux

  C program for Linux to read and write data using a shared memory

• SharedMemoryWinCpp

  C++ program for Windows to read and write data be means of shared memory

• SharedMemoryWinCSharp

  C# program for Windows to read and write data be means of shared memory

• SharedMemoryExampleExt.project/SyncExample

  The SyncExample application shows how data is read and written synchronously by means of shared memory.

• SynchronizationExample

  C++ program for Windows for synchronized reading and writing of data by means of shared memory.

  In this example, the data exchange is done by the SyncExample application.
