Thanks to both replies by now. Two points. length>>1000bits means
that i'm talking about an implementation that runs up to 1000000bits.
In the moment i'm working with a string in memory and use a state
maschine to get to the first byte, use string.struct to get
the word/long containing all bits and a little bit masking.

There is no real problem writing code for this, but i thought that
it could be that there are already implementations for bitstreams
f.e. mpeg-reading, a zlib implementation or other coding/decoding
things...

Wishing a happy day
