How the old people always make wrong, change parameter function pointer points to does not affect the function of the external argument point toInitlist (LinkList * L) is L=malloc application memory here, with the main L1 and L2 don't have any relationship between MAO
Or to use reference initlist (LinkList * & amp; L), the main of L1 and L2 to pointer LinkList * L1, * L2; Intilist (L); Other unchanged
Or with double pointer initlist (LinkList& * * L) main L1 and L2 will change to a pointer, to use * L=initlist malloc
