| XDAS_Int32(* | process )(IUNIVERSAL_Handle handle, XDM1_BufDesc *inBufs, XDM1_BufDesc *outBufs, XDM1_BufDesc *inOutBufs, IUNIVERSAL_InArgs *inArgs, IUNIVERSAL_OutArgs *outArgs) |

| XDAS_Int32(* IUNIVERSAL_Fxns::process)(IUNIVERSAL_Handle handle, XDM1_BufDesc *inBufs, XDM1_BufDesc *outBufs, XDM1_BufDesc *inOutBufs, IUNIVERSAL_InArgs *inArgs, IUNIVERSAL_OutArgs *outArgs) |
Basic audio decoding call.
| [in] | handle | Handle to an algorithm instance. |
| [in,out] | inBufs | Input buffer descriptors. |
| [in,out] | outBufs | Output buffer descriptors. |
| [in,out] | inOutBufs | Input/Output buffer descriptors. |
| [in] | inArgs | Input arguments. This is a required parameter. |
| [out] | outArgs | Ouput results. This is a required parameter. |
handle must be a valid algorithm instance handle.
inArgs must not be NULL, and must point to a valid IUNIVERSAL_InArgs structure.
outArgs must not be NULL, and must point to a valid IUNIVERSAL_OutArgs structure.
inBufs must either be NULL or point to a valid XDM1_BufDesc structure.
outBufs must either be NULL or point to a valid XDM1_BufDesc structure.
inOutBufs must either be NULL or point to a valid XDM1_BufDesc structure.
The buffers in inBufs, outBufs and inOutBufs are physically contiguous and owned by the calling application.
inArgs.
The algorithm must not modify the contents of inBufs, with the exception of inBufs.descs[].accessMask. That is, the data and buffers pointed to by these parameters must be treated as read-only.
The algorithm must appropriately set/clear the XDM1_BufDesc::descs[].accessMask field in inBufs, outBufs, and inOutBufs. For example, if the algorithm only read from inBufs.descs[0].buf using the algorithm processor, it could utilize XDM_SETACCESSMODE_READ to update the appropriate accessMask fields. The application may utilize these returned values to appropriately manage cache.
The buffers in inBufs, outBufs, and inOutBufs are owned by the calling application.
| IUNIVERSAL_EOK | Success. | |
| IUNIVERSAL_EFAIL | General failure. See IUNIVERSAL_Status::extendedError for more detailed further error conditions. | |
| IUNIVERSAL_EUNSUPPORTED | Request is unsupported. |
| XDAS_Int32(* IUNIVERSAL_Fxns::control)(IUNIVERSAL_Handle handle, IUNIVERSAL_Cmd id, IUNIVERSAL_DynamicParams *params, IUNIVERSAL_Status *status) |
Control behaviour of an algorithm.
| [in] | handle | Handle to an algorithm instance. |
| [in] | id | Command id. See XDM_CmdId. |
| [in] | params | Dynamic parameters. This is a required parameter. |
| [out] | status | Output results. This is a required parameter. |
handle must be a valid algorithm instance handle.
params must not be NULL, and must point to a valid IUNIVERSAL_DynamicParams structure.
status must not be NULL, and must point to a valid IUNIVERSAL_Status structure.
If a buffer is provided in the status->data field, it must be physically contiguous and owned by the calling application.

If a buffer was provided in the status->data field, it is owned by the calling application.
