[in] | handle | Handle to an algorithm instance. |
[in,out] | inBufs | Input buffer descriptors. |
[in,out] | outBufs | Output buffer descriptors. The algorithm may modify the output buffer pointers. |
[in] | inArgs | Input arguments. This is a required parameter. |
[out] | outArgs | Ouput results. This is a required parameter. |

[].accessMask field in both inBufs
