Woolz objects domains and values maintain a linkcount, which records it's usage by other objects, domains or values. To increment a linkcount the appropriate assignment function should be used. More...

Functions
WlzObject *	WlzAssignObject (WlzObject obj, WlzErrorNum dstErr)
	Assign an object (increment it's linkcount) by first checking for NULL, then the value of linkcount, before incrementing the linkcount. If used concientiously, assignment should avoid memory errors. More...

WlzCompoundArray *	WlzAssignCompoundArray (WlzCompoundArray obj, WlzErrorNum dstErr)
	Assign a compound array (increment it's linkcount) by first checking for NULL, then the value of linkcount, before incrementing the linkcount. If used concientiously, assignment should avoid memory errors. More...

WlzDomain	WlzAssignDomain (WlzDomain domain, WlzErrorNum *dstErr)
	Assign a domain by incrementing it's linkcount. More...

WlzValues	WlzAssignValues (WlzValues values, WlzErrorNum *dstErr)
	Assign a values by incrementing it's linkcount. More...

WlzProperty	WlzAssignProperty (WlzProperty property, WlzErrorNum *dstErr)
	Assign a property by incrementing it's linkcount. More...

WlzPropertyList *	WlzAssignPropertyList (WlzPropertyList pList, WlzErrorNum dstErr)
	Assigned a Woolz property list, incrementing the link count or the number of times the property list is used. More...

WlzAffineTransform *	WlzAssignAffineTransform (WlzAffineTransform trans, WlzErrorNum dstErr)
	Assign an affine transform by incrementing it's linkcount. More...

WlzTransform	WlzAssignTransform (WlzTransform t, WlzErrorNum *dstErr)
	Assign a transform by incrementing it's linkcount. More...

WlzThreeDViewStruct *	WlzAssign3DViewStruct (WlzThreeDViewStruct viewStr, WlzErrorNum dstErr)
	Assign an woolz 3D view structure by incrementing it's linkcount. More...

WlzBoundList *	WlzAssignBoundList (WlzBoundList blist, WlzErrorNum dstErr)
	Assign a boundary list by incrementing it's linkcount. More...

WlzPolygonDomain *	WlzAssignPolygonDomain (WlzPolygonDomain poly, WlzErrorNum dstErr)
	Assign a polygon domain by incrementing it's linkcount. More...

WlzGMModel *	WlzAssignGMModel (WlzGMModel model, WlzErrorNum dstErr)
	Assign a geometric model by incrementing it's linkcount. More...

int	WlzUnlink (int linkcount, WlzErrorNum dstErr)
	Unlink an object, domain or values by decrementing and testing it's linkcount. More...
