104 In this example, only the producer head and tail (prod_head and prod_tail) are modified,
107 The initial state is to have a prod_head and prod_tail pointing at the same location.
112 First, *ring->prod_head* and ring->cons_tail are copied in local variables.
211 In this example, only the producer head and tail (prod_head and prod_tail) are modified.
213 The initial state is to have a prod_head and prod_tail pointing at the same location.
218 On both cores, *ring->prod_head* and ring->cons_tail are copied in local variables.
238 * If ring->prod_head is different to local variable prod_head,
241 * Otherwise, ring->prod_head is set to local prod_next,
273 A core can only update it if ring->prod_tail is equal to the prod_head local variable.
