Surprising that lseek's return value is not marked warn_unused_result.
Probably because it's guaranteed not to fail because of I/O errors:
ERRORS
EBADF fd is not an open file descriptor.
EINVAL whence is not one of SEEK_SET, SEEK_CUR, SEEK_END;
or the resulting file offset would be negative, or
beyond the end of a seekable device.
EOVERFLOW
The resulting file offset cannot be represented in an
off_t.
ESPIPE fd is associated with a pipe, socket, or FIFO.
