I'm trying to write to a file using fprintf_s a value of type unsigned long
long, using the format specifiers "%ld". However, when I open the text
file, I see incorrect values. I think I am using the wrong type specifiers.
I can't find the correct information in the help section. Does anyone know
what format specifiers I need to use? Here is my code:

fprintf_s(cfPtr, "%lu\n", number);

%ld is plain vanilla long. You want %llu or %I64u

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

I just tried those two suggestions, but I still get the same problem.

Show your code, what you expect to see, and what you actually see in the
file.

It's very hard to be 100% portable with this:
VC++: %I64u or %llu
GNU g++, Solaris: %llu
Borland: %Lu or I64u
