Opens an interprocess event handle exported from another process with cudaIpcGetEventHandle. This function returns a cudaEvent_t that behaves like a locally created event with the cudaEventDisableTiming flag specified. This event must be freed with cudaEventDestroy. Performing operations on the imported event after the exported event has been freed with cudaEventDestroy will result in undefined behavior. IPC functionality is restricted to devices with support for unified addressing on Linux operating systems.
