FIND_NEXT_BEST_NODE(9) Memory Management in Linux FIND_NEXT_BEST_NODE(9)NAME
find_next_best_node - find the next node that should appear in a given node's fallback list
SYNOPSIS
int find_next_best_node(int node, nodemask_t * used_node_mask);
ARGUMENTS
node
node whose fallback list we're appending
used_node_mask
nodemask_t of already used nodes
DESCRIPTION
We use a number of factors to determine which is the next node that should appear on a given node's fallback list. The node should not have
appeared already in node's fallback list, and it should be the next closest node according to the distance array (which contains arbitrary
distance values from each node to each node in the system), and should also prefer nodes with no CPUs, since presumably they'll have very
little allocation pressure on them otherwise. It returns -1 if no node is found.

Blt_TreeDeleteNode(3) BLT Library Procedures Blt_TreeDeleteNode(3)__________________________________________________________________________________________________________________________________________________NAME
Blt_TreeDeleteNode - Deletes a node and its descendants.
SYNOPSIS
#include <bltTree.h>
Blt_TreeNode
Blt_TreeDeleteNode(tree, node)
ARGUMENTS
Blt_Tree tree (in) Tree containing the node.
Blt_TreeNode node (in) Node to be deleted.
_________________________________________________________________DESCRIPTION
This procedure deletes a given node and all it descendants from a tree data object.
The arguments are as follows:
tree The tree containing the parent node.
node Node to be deleted. The node and its descendant nodes are deleted. Each node's data values are deleted also. The reference
count of the Tcl_Obj is decremented.
Since all tree objects must contain at least a root node, the root node itself can't be deleted unless the tree is released and destroyed.
Therefore you can clear a tree by deleting its root, but the root node will remain until the tree is destroyed.
RETURNS
Always returns TCL_OK. Errors generated in a notification callbacks are backgrounded (see Tcl_TreeCreateNotifyHandler).
EXAMPLE
The following example deletes the root node.
Blt_TreeNode root;
root = Blt_TreeRootNode(token);
Blt_TreeDeleteNode(token, root);
NOTIFICATIONS
Blt_TreeDeleteNode can trigger tree notify events. You can be notified whenever a node is deleted by using the Blt_TreeCreateNotifyHan-
dler. A callback routine is registered that will be automatically invoked whenever a node is deleted via Blt_TreeDeleteNode to the tree.
KEYWORDS
tree, token
