NAME
     SoPathList (SoPathList) - maintains a list of pointers to paths

INHERITS FROM
     SbPList > SoBaseList > SoPathList

SYNOPSIS
     #include <Inventor_c/SoLists.h>

	  Functions from class SoPathList:

     SoPathList *	 SoPathListCreate()
     SoPathList *	 SoPathListCreateSize(int size)
     void		 SoPathListDelete(SoPathList *this)
     void		 SoPathListAppend(SoPathList *this, SoPath *path)
     SoPath *		 SoPathListUnknownOperator(const SoPathList *this, int
			      i)
     SoPathList *	 SoPathListCopy(SoPathList *this, const SoPathList *l)
     int		 SoPathListFindPath(SoPathList *this, const SoPath
			      *path)
     void		 SoPathListSort(SoPathList *this)
     void		 SoPathListUniquify(SoPathList *this)

	  Functions from class SoBaseList:

     void		 SoPathListInsert(SoPathList *this, SoBase *ptr, int
			      addBefore)
     void		 SoPathListRemove(SoPathList *this, int which)
     void		 SoPathListTruncate(SoPathList *this, int start)
     void		 SoPathListSet(SoPathList *this, int i, SoBase *ptr)
     void		 SoPathListAddReferences(SoPathList *this, SbBool
			      flag)

	  Functions from class SbPList:

     int		 SoPathListFind(const SoPathList *this, const void
			      *ptr)
     int		 SoPathListGetLen(const SoPathList *this)
     int		 SoPathListIsEq(const SoPathList *this, const SbPList
			      *pl)
     int		 SoPathListIsNEq(const SoPathList *this, const SbPList
			      *pl)

DESCRIPTION
     This subclass of SoBaseList holds lists of pointers to SoPaths. It
     updates reference counts to paths in the list whenever adding or removing
     pointers.

FUNCTIONS
     SoPathList *	 SoPathListCreate()
	  Constructor.

SoPathList(3IV)

     SoPathList *	 SoPathListCreateSize(int size)
	  Constructor that pre-allocates storage for size pointers.

     void		 SoPathListDelete(SoPathList *this)
	  Destructor.

     void		 SoPathListAppend(SoPathList *this, SoPath *path)
	  Adds a path to the end of the list.

     SoPath *		 SoPathListUnknownOperator(const SoPathList *this, int
			      i)
	  Accesses an element of a list.

     SoPathList *	 SoPathListCopy(SoPathList *this, const SoPathList *l)
	  Copies a list, keeping all reference counts correct.

     int		 SoPathListFindPath(SoPathList *this, const SoPath
			      *path)
	  Returns the index of the matching path in the list, or -1 if not
	  found.

     void		 SoPathListSort(SoPathList *this)
	  Sorts list in place based on (1) increasing address of head node,
	  then (2) increasing indices of children.

     void		 SoPathListUniquify(SoPathList *this)
	  Given a sorted list, removes any path that (1) is a duplicate, or
	  (2) goes through a node that is the tail of another path.
