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...
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...

Detailed Description

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.
