 * \brief The calculation of the Mean interface requires the developer to reserve or apply for temporary space. The
 * relationship between the maximum temporary space (maxTmpBuffer) and the space occupied by the input (inputSize x
 * typeSize) is as follows: maxTmpBuffer = maxLiveNodeCount * inputSize * typeSize + extraBuf
 * This interface is used to obtain maxLiveNodeCount and extraBuf.

 * \param [in] typeSize, size of the input data type, in bytes
 * \param [out] maxLiveNodeCount, the multiple of the maximum temporary space to the input occupied space
 * \param [out] extraBuf, the size of the extra temporary space
