null in c
This is going off-topic a bit, but two ways to represent 0C in C strings
are: 

- Do not use *char but operate on the byte level. Since C let's you work
on a string even if it contains 0C (although not with the standard
string libraries, functions and operations), you could return a struct
that gives the length and the memory area.

Thus 'a0Cb0C0Cd' would become (6, 'a0Cb0C0Cd')

- Use an array of strings where every 0C will move to the next item and
give length of array. You will need a sentinel at the end for the last
0C. 

Thus 'a0Cb0C0Cd' would become (4, 'a0C', 'b0C', '0C, 'd0C')

So it is doable, but not easy...

Best regards
Michael
