- * FUNCTION: pkix_PolicyNode_GetChildrenMutable
- * DESCRIPTION:
- *
- *  Retrieves the List of PolicyNodes representing the child nodes of the
- *  Policy Node pointed to by "node" and stores it at "pChildren". If "node"
- *  has no List of child nodes, this function stores NULL at "pChildren".
- *
- *  Note that the List returned by this function may be mutable. This function
- *  differs from the public function PKIX_PolicyNode_GetChildren in that
- *  respect. (It also differs in that the public function creates an empty
- *  List, if necessary, rather than storing NULL.)
- *
- *  During certificate processing, children Lists are created and modified.
- *  Once the list is accessed using the public call, the List is set immutable.
- *
- * PARAMETERS:
- *  "node"
- *      Address of PolicyNode whose child nodes are to be stored.
- *      Must be non-NULL.
- *  "pChildren"
- *      Address where object pointer will be stored. Must be non-NULL.
- *  "plContext"
- *      Platform-specific context pointer.
- * THREAD SAFETY:
- *  Conditionally Thread Safe
- *  (see Thread Safety Definitions in Programmer's Guide)
- * RETURNS:
- *  Returns NULL if the function succeeds.
- *  Returns a PolicyNode Error if the function fails in a non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.

- * FUNCTION: pkix_PolicyNode_ToString_Helper
- * DESCRIPTION:
- *
- *  Produces a String representation of a PolicyNode tree below the PolicyNode
- *  pointed to by "rootNode", with each line of output prefixed by the String
- *  pointed to by "indent", and stores the result at "pTreeString". It is
- *  called recursively, with ever-increasing indentation, for successively
- *  lower nodes on the tree.
- *
- * PARAMETERS:
- *  "rootNode"
- *      Address of PolicyNode subtree. Must be non-NULL.
- *  "indent"
- *      Address of String to be prefixed to each line of output. May be NULL
- *      if no indentation is desired
- *  "pTreeString"
- *      Address where the resulting String will be stored; must be non-NULL
- *  "plContext"
- *      Platform-specific context pointer.
- * THREAD SAFETY:
- *  Conditionally Thread Safe
- *  (see Thread Safety Definitions in Programmer's Guide)
- * RETURNS:
- *  Returns NULL if the function succeeds.
- *  Returns a PolicyNode Error if the function fails in a non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.

- * FUNCTION: pkix_PolicyNode_DuplicateHelper
- * DESCRIPTION:
- *
- *  Duplicates the PolicyNode whose address is pointed to by "original",
- *  and stores the result at "pNewNode", if a non-NULL pointer is provided
- *  for "pNewNode". In addition, the created PolicyNode is added as a child
- *  to "parent", if a non-NULL pointer is provided for "parent". Then this
- *  function is called recursively to duplicate each of the children of
- *  "original". At the top level this function is called with a null
- *  "parent" and a non-NULL "pNewNode". Below the top level "parent" will
- *  be non-NULL and "pNewNode" will be NULL.
- *
- * PARAMETERS:
- *  "original"
- *      Address of PolicyNode to be copied; must be non-NULL
- *  "parent"
- *      Address of PolicyNode to which the created node is to be added as a
- *      child; NULL for the top-level call and non-NULL below the top level
- *  "pNewNode"
- *      Address to store the node created; should be NULL if "parent" is
- *      non-NULL and vice versa
- *  "plContext"
- *      Platform-specific context pointer.
- * THREAD SAFETY:
- *  Conditionally Thread Safe
- *  (see Thread Safety Definitions in Programmer's Guide)
- * RETURNS:
- *  Returns NULL if function succeeds
- *  Returns a PolicyNode Error if the function fails in a non-fatal way.
- *  Returns a Fatal Error if the function fails in a fatal way
