Function Documentation

mcl_error_t data_lake_json_from_objects	(	data_lake_object_t **	object_array,
		mcl_size_t	array_size,
		const char *	client_id,
		const char *	subtenant_id,
		char **	json
	)

This function generates a json string from an array of datalake objects.

Parameters

[in]	object_array	Array of data lake objects.
[in]	array_size	Size of array.
[in]	client_id	Client ID.
[in]	subtenant_id	Subtenant ID.
[out]	json	Json body for the request which is needed to generate upload urls.

Returns

• MCL_OK in case of success.
• MCL_OUT_OF_MEMORY in case there is not enough memory in the system to proceed.
• MCL_INVALID_PARAMETER in case there is no path to generate upload url.
• MCL_FAIL in case of an internal error in MCL.

		mcl_size_t	json_size,
		mcl_size_t	client_id_length
	)

This function is used to match signed urls with objects.

Parameters

[in]	object_array	Array of data lake objects.
[in]	array_size	Size of array.
[in]	json	Json string to parse, does not need to be NULL terminated.
[in]	json_size	Size of json string.
[in]	client_id_length	Length of Client ID.

Returns

• MCL_OK in case of success.
• MCL_DATA_LAKE_SIGNED_URL_GENERATION_FAIL if signed URL could not be retrieved for all data lake objects with non-NULL paths.
• MCL_OUT_OF_MEMORY in case there is not enough memory in the system to proceed.
• MCL_FAIL in case of an internal error in MCL.
