Hi I just need to now how to set the memory area free.
I know I can use the free() funktion to do that. But how I have to write for a pointer array?

Here is the code:

Code:
typedef struct GRAPH
{
	POINT **points; // Knoten-Array
	
} GRAPH;

void f_create_graph(var num_points)
{
	// create
	
	GRAPH* graph = malloc(sizeof(GRAPH));
	
	graph.points = (POINT **)malloc(num_points * num_points * sizeof(POINT*));

	// set free
	
	free(graph.points);
	
	free(graph);
}


I think free(graph.points); is incorrect to set the complete pointer array free, or is it right?
