Probably - just checked my only glibc source (2.0.99) and it does return
loff_t. However, if its not prototyped, then GCC will default it to return
an int.
Therefore, there are still two errors on the program:
1. It's passing a FILE * instead of an int as the first argument.
2. The C compiler believes, since there is no prototype to tell it otherwise,
that llseek returns an int.
1 can be fixed by using fseeko64 - there is no fseek64 in that version of glibc,
nor the later glibc headers.
2 can be fixed merely by supplying the appropriate prototype:
loff_t __llseek (int fd, loff_t offset, int whence);
