     #include <Inventor_c/actions/SoPickAction.h>

     typedef SoPickAction  SoPickAct

	  Functions from class SoPickAction:

     void		       SoPickActSetVPReg(SoPickAct *this, const
				    SbViewportRegion *newRegion)
     const SbViewportRegion *  SoPickActGetVPReg(const SoPickAct *this)

	  Functions from class SoAction:

     void		 SoPickActDelete(SoPickAct *this)
     void		 SoPickActApply(SoPickAct *this, SoNode *node)
     void		 SoPickActApplyPath(SoPickAct *this, SoPath *path)
     void		 SoPickActApplyPathList(SoPickAct *this, const
			      SoPathList *pathList, SbBool obeysRules = FALSE)
     SoType		 SoPickActGetClassTypeId()
     SoType		 SoPickActGetTypeId(SoPickAct *this)
     SbBool		 SoPickActIsOfType(SoPickAct *this, SoType type)
     void		 SoPickActInvalidateState(SoPickAct *this)

DESCRIPTION
     This is an abstract base class for all picking actions. Currently, the
     only supported subclass is the SoRayPickAction.

FUNCTIONS
     void		       SoPickActSetVPReg(SoPickAct *this, const
				    SbViewportRegion *newRegion)
     const SbViewportRegion *  SoPickActGetVPReg(const SoPickAct *this)
	  Sets/returns current viewport region to use for action. Even though
	  the picking operation may not involve a window per se, some nodes
	  need this information to determine their size and placement.
