Prim Linking Function

Is there a function that links prims together based on the prims' names? For example, if we have prim A, prim B, and prim C all alligned in a line like A-B-C where prim B would be the root prim, is there a function that I could give to prim A and prim C that would link them to prim B and also a function that unlinks the two from prim B? I've been searching through the LSL wiki looking for a solution, but if someone could point me in the right direction, it would be much appreciated~ Thanks.
