adas_fusion_algo_close_t

Close an instance of an algorithm

Synopsis:

#include <adas/adas_fusion_defs.h>

typedef adas_error_t(* adas_fusion_algo_close_t)(adas_fusion_algo_handle_t algo_handle);

Arguments:

algo_handle: An algorithm handle generated by the call to adas_fusion_algo_open_t.

Library:

libadas

Description:

This function is called to destroy an existing instance of an algorithm. It needs to free any memory associated with this instance.

Returns:

ADAS_EOK when the function successfully completes, otherwise another adas_error_t value that provides the reason that the call failed.
