You're trying to convert a pointer to unsigned char to a pointer to plain char. That doesn't work. Your code is faulty.

fred = (unsigned char*)mychar;

something like that cast might help.

[CornedBee]

Bad idea. Never cast unless you know for certain that it's justified. Careless casting away of conversion errors is an extremely bad habit to get into.

[wossname]

Fair point, I suggest it only in the absence of any code example that we can make a more informed suggestion upon.

Help you in compiling?

How about you post the code that makes problems. As you can see from our discussion, our clairvoyance is not quite in tune.
