Oh I see. Have to keep this hack in mind for older
versions. The new program with the my_llseek() function
did work, while the previous on with llseek() didn't, probably
because of lack of header file.
Your new prog compiles with no warnings. FWIW, the old one
compiles on one of my devel systems (Mdk7.1) with:
gcc -Wall llseek.c
llseek.c: In function `main':
llseek.c:26: warning: implicit declaration of function `llseek'
/tmp/cc5hxKQD.o: In function `main':
/tmp/cc5hxKQD.o(.text+0x8a): the `llseek' function may be dangerous; use
`lseek64' instead.
Wonder why the linker reports llseek is dangerous?
