if lseek is libc and not available why is the symbol for lseek in the
kext symbol file?

The function definition is not in unistd.h as the man page
indicates ... ergo compile error.
But, inspection of the KEXT symbol file shows lseek.
So, can someone tell me how to use lseek from my KEXT?
Can't be done. lseek is a libc function, and libc is generally not
available in kernel extensions. If you have file operations to do, use
a user-mode application, where libc is available.
