how to use lseek() system call with over 2G files?

[Alex]

Hi everybody!

Some time ago there wasn't any possibility to create disk file larger 
than 2G and there was no problem with lseek().
But as for now we can do it but I looked into headers and found off_t is 
equal to long -> no more than 2G on i386 machines.
As far as lseek() is a system call I cannot believe it cannot be used 
with larger files but how?

Maybe it's a silly question? :0)
