Ok, the plot thickens -- did you cast the address of the pointer to a char* 
to pass to fwrite? Maybe a dumb question but I'm just feeling this out.
You have p being of some type T* and you say
    fwrite(fp, (char*)p, sizeof(T));
Is this done in a template function where you don't know the final type of 
T?
What is T anyway?
I'm just hoping some funny pointer arithmetic is not getting done on p 
because you are passing it around as different types.
Any progress?

Basically what I did was used a templated function to write, then I write 
the arg with fwrite, and use sizeof(T) to get the size. Reading does the 
same thing, I also overloaded operators << and >> to read and write.
