Hello,
I'm considering adding a function that work just like a Read but without
changing the current position of the file. Reading data and then seeking
back is a common situation so that having a function that just reads the
current data without altering the position makes sense. It's of interest
for
codecs but will come handy also when using it in a multithread
environment
making less trickier to synchronize the calls.

Don't BPositionIO::{Read,Write}At already do this?


From the BDataIO point of view there's not a way to do that. But, yes, it's
not something to care about as it seems in the end we are always forced to
use something derived from BPositionIO.
