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