`InputParams` (`input`)
		A pointer to a module implementation-specific structure containing parameters to be interpreted in a function-specific manner by the requested DL module.
`OutputParams` (`output`)
		A pointer to a module, implementation-specific structure containing the output data. The service provider will allocate the memory for this structure. The application should free the memory for the structure.
