After used ACAPI_Element_UnLink to delete all links of an element , the number of the links got by ACAPI_Element_GetLinks is still not zero.
(The links is created and deleted by the same add-on, alos set undo functions )

Are you first callingACAPI_Element_GetLinksto retrieve a list of linked elements, and then repeatedly calling ACAPI_Element_UnLinkto remove each link? Does ACAPI_Element_UnLinkreturn an error? And are you sure the guid_linkFromand guid_linkToparameters are in the right order?

Yes, I am first callingACAPI_Element_GetLinks, and then calling ACAPI_Element_UnLinkone by one, and sure ACAPI_Element_UnLinkreturns no error, and sure parameters are in the right order
