| PST SDK 6.0.0.0-272350a

sharedmemory.cs

This example can be found in `examples\csharp\sharedmemory\sharedmemory.cs`. When the PST SDK has been installed through the PST Software Suite installer the examples can be found in the Development folder.

This example shows how to activate the shared memory communication pipeline that enables communication of the PST Client application through the PST SDK. Note that for the shared memory pipeline to function, the application has to run with elevated access (administrator rights). After enabling shared memory, the PST Client application can be used to download calibration information and manage tracking targets.

When compiling and running this example, please make sure that the required dependencies can be found by the executable (e.g. by copying the `Redist` directory into the build directory. When the PST SDK has been installed through the PST Software Suite installer the Redist folder can be found in the Development folder.).
