It is supossed that no memory is allocated for sequence. If we are not sure better use function bufrdeco_clean_subset_sequence_data

bufrdeco_substitute_tables()

int bufrdeco_substitute_tables	(	struct bufr_tables **	replaced,
		struct bufr_tables *	source,
		struct bufrdeco *	b
	)

substitute an struct bufr_tables into a struct bufrdeco

Parameters

replaced	Pointer where to set the replaced pointer
source	Pointer to a struct bufr_tables
b	pointer to the container basic struct bufrdeco

Returns

0 if succeeded, 1 otherwise

Remember that the struct bufr_tables used in bufrdeco library is the one which pointer is in struct bufrdeco . To avoid problems the struct must be initialized before substituted in this fucntion. Both source and replaced structs are not modified.

This is useful if we do not want to read and parse tables again if the caller has a pool of already readed tables.
