Mandatory

When you derive from a KcsXform class, the mandatory external entry points are:

extern

long KcsDLOpenXfrmCount; KcsXform * KcsCreateXfrm(KcsStatus *aStat, 

	KcsChunkSet *aChunkSet, KcsChunkId aChunkId,  	KcsAttributeSet

*aAttrSet);

KcsCreateXfrm()() creates an instance of a KcsXform derivative.
