Hello all,
i am using the mmap module (python2.4) to access contents of a file.
My question regards the relative performance of mmap.seek() vs
mmap.tell(). I have a generator that returns stuff from the file,
piece by piece. Since other things may happen to the mmap object in
between consecutive next() calls (such as another iterator's next()),
i have to store the file position before yield and restore it
afterwards by means of tell() and seek(). Is this correct?
When restoring, is there a penalty for mmap.seek(pos) where the file
position is already at pos (i.e., nothing happened to the file
position in between, a common scenario)? If there is, is it worth
doing
if mmap.tell() != pos:
mmap.seek(pos)
or such?
Cheers!
