Re: [Boost-users] base 64 encoding

But there is still the problem with running off the end of the source -
If the source is not a multiple of 3 bytes then the input iterator will
run off the end of the input sequence which can cause an error.

I had to separately record the number of bytes.  Then when I decode,
just pull off that number of bytes.

        Hi,

        I'm trying to encode base64 data by composing base64_from_binary
with transform_width but this doesn't appear to work correctly when the
data is not a multiple of 3 long. What is the correct way to handle this
- do I have to handle the padding myself by extending the input data and
then patching the tail of the result?

           Thanks

               Andrew
