C file functions in QB64 ???

[DSMan195276]

I think I know why you are having a problem, you must be using the 32-bit version of QB64
if that's the case then try the code below

The second version works, also with the 64 bit version.

What have you changed? At first glance I don't see it, maybe at second glance.

It's the `size` and `count` parameters to `fread()`, they're a different size. In C they're a `size_t` type, which is a 32-bit integer on 32-bit system and a 64-bit integer on 64-bit system.

If you want to avoid separate definitions then you could use `_Unsigned _Offset` for the `size_t` parameters, that's more or less the same thing.
