PS: Can anyone recommend a good reference to the POSIX standard?
I have heard good things said about Zlotnick's book, albeit
from people that thought Unix was a strange new thing. The
standard itself (ISO 8859-1:1990, not the latest rev of IEEE
POSIX.1) is not much worse than Unix manpages, and probably
doesn't contain too may surprises in the file system.
The "file positioning functions" fseek, ftell, fsetpos, and
fgetpos are all in ANSI C, and not discussed at all in POSIX.
fseek and ftell use "long ints" and are retained for historical
reasons. New programs that want to movin into the new
multi-gigabyte file world should probably use fsetpos and
fgetpos.
