Not enough information.

Are the values token4 =  0 & token5 = 32 the values passed into func(), or the values returned by func()?

Because if those are the values coming out of func(), your C program is broken:

  1. 0 & 95 = 0. (0 & anything == 0)
  2. 32 & 32 = 32. (X & X) always == X
  3. 32 & 128 = 0.
  4. 0 | 32 | 0 = 32.

But if the values you've given are the values going into func(), then as you've only supplied a declaration (was that form ever legal C?), we cannot tell what might come out for those inputs.

Further more, the only way I can interpret that declaration of func(), is that it is expecting a pointer to an unsigned char as its input. And the likelyhood of 0 and 32 being valid pointers is minimal.
