node_free() static void node_free ( RTreeNode *  node ) static Frees the memory allocated for an RTree node and its associated resources. This function recursively frees the memory of an RTree node. If the node is a branch node, it first recursively frees all child nodes. After handling the child nodes, it frees the memory allocated for the STBoxes and the arrays of boxes and child nodes within the current node. Finally, it frees the memory allocated for the node itself. Parameters [in] node Pointer to the RTreeNode structure to be freed.
