> count++, ptr++ Also, you should avoid this; it adds a extra addition per iteration for no real benefit. Try: p = ptr - 1 # also avoid branching[0] over p++ body: p++ if *p != 0 goto body return p - ptr 0: I assume a single addition is cheaper than a unconditional branch, which is probable, but not nearly as big a difference as with conditional branches.
