get_vroom_matrix()

void get_vroom_matrix	(	char *	sql,
		Vroom_matrix_t **	rows,
		size_t *	total_rows,
		bool	is_plain
	)

Reads the VROOM matrix.

Parameters

[in]	sql	SQL query that has the following columns: start_id, end_id, duration, cost
[in]	is_plain	Whether the plain or timestamp function is used
[out]	rows	C Container that holds all the matrix rows
[out]	total_rows	Total rows recieved

cost is not mandatory
