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

That isn't a lot of help, is the data textual (does it look like the
above in an editor), or raw data?

If it is the former, you can probably just cast to char* and print it,
otherwise you have to know the exact format of the data in oder to
convert it into something meaningful.
