Unmaps the buffer object specified by buffer for access by CUDA.
There must be a valid OpenGL context bound to the current thread when this function is called. This must be the same context, or a member of the same shareGroup, as the context that was bound when the buffer was registered.
Stream hStream in the current CUDA context is synchronized with the current GL context.
- Parameters:
-
| buffer | - Name of the buffer object to unmap |
| hStream | - Stream to synchronize |
- Returns:
- CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
