Last buffer isn't written at all: you might want to try adding
fflush() every 1000 bytes from 4 294 950 000, every 100 bytes from 
4 294 960 000, and maybe every 10 bytes from 4 294 963 200, as you may
only get up to 4GB-4KB == 4 294 963 200 written, but may get to 4GB-6
== 4 294 967 290 (limit due to writing 10 bytes a time), and might
have to write and fflush a byte at a time to get further than that. 
You could try something like:

<    count += ret;
>    count += ret;
>    if ((count >= 4294950000ULL && !(count%1000ULL))
>     || (count >= 4294960000ULL && !(count%100ULL))
>     || (count >= 4294963200ULL && !(count%10ULL)))
>        fflush(f);
