I am trying to read a binary file and do some analysis of the information contained.  I am using fread(name,4,1,fp) where name is a char[4], name is supposed to receive whatever I read in, but I can't make sense of what is read in.  Can someone help me read this information in and analyze it?
Thanks

A. Start by creating a simple test file that contains something like "ABCD" and use that file to test your code.

B. Use your debugger if you can to inspect the name[] string after the fread().  If you can't use your debugger, please specify what compiler and operating system you are using and I will try to help further.

C. If the above test doesn't work, give me a sample of the code starting with the fopen().  By the way are you opening the file in binary mode?

D. If the test does work, let me know what you are trying to analyze or accomplish if you need further assistance.

I was able to figure the problem and it wasn't a coding error.  I was using Visual C++ 6.0 and for some reason, the debugger couldn't show what was in the variables, I could see it in memory but it wasn't shown by the memory.

I changed to UNIX and was able to see the contents of the variables clearly,

thanks
