Hi all, I am learning C, and I have a problem with printf.
I have a pointer that points to binary data, and I want to print that
data
out. If I cast the pointer to (char *) then the data is printed out in
the UniCode(?) equivalent of the data.
If I try to cast to (int *) then I only get the address of the pointer
(I
think). What I really want is all the ones and zeros to be printed
out.

What is the exact type of the pointer?
Void

"Binary data" is term that has
had several different meanings in various posts. What does the
pointer really point to?
Binary data, 1's and 0's
I can interpret the data, if I can read it.

Give a short example if possible.

1111 1010 1100 1110

If you know the length of the array, you may want to print each element
(byte) of the array as an hex value.



Awesome, thats what I can do.
How do I find the length of the array?

You can't. You have to keep track of it since the beginning (i.e. while
storing data in it).
