GetPointer
OpenLvVision_OpenCv.lvlib:Cuda.lvlib:HostMem.lvclass:HostMem GetPointer.vi
Retruns the raw memory pointer to the underlying pinned data buffer of the HostMem object. This allows you to directly access or reuse this memory in other libraries without unnecessary data copying.
| error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
| status The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
| code The code input identifies the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
| source The source string describes the origin of the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
| HostMem in |
| error out The error out cluster passes error or warning information out of a VI to be used by other VIs. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
| status The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
| code The code input identifies the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
| source The source string describes the origin of the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |

| PointerData Memory description of a CUDA-pinned host memory for zero-copy interop. |
| DataPtr The absolute memory address of the first pixel in the image (top-left, coordinate 0,0) |
| Step Also known as the Stride or Line Pitch. This represents the number of bytes between the start of one row and the start of the next row |
| TotalBytes The total physical footprint of the image in RAM. It is calculated as step * rows |
| Cols The horizontal width of the image in pixels |
| Rows The vertical height of the image in pixels |
| ElemSize The number of bytes occupied by a single pixel |
| cvType The internal OpenCV integer constant representing the data format |
| Channels The number of components per pixel |
