Add support to handle multiple hooks #392

Closed codehz closed 6 years ago

codehz commented 6 years ago

Example:

A is original function. => means call origin function -> means indirect call by function pointer

  1. Hook (A, B, B0) call hook_impl(A, B, B0) hooks: (A, (B, B0)) // B => B0 -> A

  2. Hook (A, C, C0) C0 = B0 *B0 = C hooks: (A, (C, C0)) // B => B0 -> C => C0 -> A

  3. Hook (A, D, D0) D0 = C0 *C0 = D hooks: (A, (D, D0)) // B => B0 -> C => C0 -> D => D0 -> A
