Your question isn't specific enough, so I'll just guess. Let's say
"int". In 32 bit, AFAIK it's  4 byte, but in 64 bit (like IA 64, not
sure if it's x64) it's 8 byte. So, if you just say "int", you will
likely getting screwed up.

By using types like u_int or something like that, you pretty much say
"I mean 4 byte kind of integer" etc
