WaitSemaphore property

Pointer<NativeFunction<OrtStatusPtr Function(Pointer<OrtExternalResourceImporter> importer, Pointer<OrtExternalSemaphoreHandle> semaphore_handle, Pointer<OrtSyncStream> stream, Uint64 value)>> WaitSemaphore

\brief Wait on an external semaphore on the EP's stream.

Inserts a wait operation into the EP's stream that blocks until the semaphore reaches the specified value. This is used to synchronize with external GPU work (e.g., D3D12 timeline fence).

\paramin importer The OrtExternalResourceImporter instance. \paramin semaphore_handle The imported external semaphore. \paramin stream The OrtSyncStream to wait on. \paramin value The fence/semaphore value to wait for.
