void iMesh_addPrntChld ( iMesh_Instance  instance,
iBase_EntitySetHandle  parent_entity_set,
iBase_EntitySetHandle  child_entity_set,
int *  err 
)

Add parent/child links between two sets.

Add parent/child links between two sets. Makes parent point to child and child point to parent. (Cycles in Set-Inclusion and Parent-Child structures.)

Parameters:
[in]instanceiMesh instance handle
[in]parent_entity_setPointer to parent set
[in]child_entity_setPointer to child set
[out]errReturned Error status (see iBase_ErrorType)
