hi all, i have seen many places in kernel where the variables specially the structures should be of fixed size independent of the architecture. i went through the definitions of them but dint get clearly (or frankly say ...dint get them even a bit) .
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 -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
