Uh, yeah, for example to pass it to fseek:

 - Function: int fseek (FILE *STREAM, long int OFFSET, int WHENCE)

But the system does like to do it as well, for example in ftell:

 - Function: long int ftell (FILE *STREAM)

It surely is.  Everyone who knows LFS would say that :)

This is something that the world at large has recognized and attacked, and
is actually working on to resolve.  LFS is very careful (you might say
cowardish) in not breaking anything that worked before, which we would not
care about so much, but others had to.  In any case, trying to be different
here just to push the world further and faster towards the goal of off_t
cleanliness is an unnecessary burden for us, as people are aware of this
problem and actually fixing their code gradually (so this is different
from MAXPATHLEN for example).
