Is there any possibility that we can extend this and use it for any data? Also does anyone know where is the documentation for both transform_width and base64 iterator where I can find their usage? I struggled a lot to get this example working. ________________________________ From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Eames, Andrew Sent: Tuesday, August 26, 2008 1:48 PM To: boost-users@lists.boost.org Subject: Re: [Boost-users] base64_from_binary Q I reported this problem a few months ago - apparently it is a feature that this only works on input data that is a multiple of 3 bytes long Andrew From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Terdale, Shantibhushan Sent: Tuesday, August 26, 2008 12:16 PM To: boost-users@lists.boost.org Subject: [Boost-users] base64_from_binary Q I am using this sample to prove myself that base64_from_binary and binary_from_base64 can be used in my app. But I am having little problem and not able to understand whats missing Here is the sample #include "boost/archive/iterators/base64_from_binary.hpp" #include "boost/archive/iterators/binary_from_base64.hpp" #include "boost/archive/iterators/transform_width.hpp" #include <string> #include <iostream> using namespace std; using namespace boost::archive::iterators; typedef base64_from_binary< transform_width<std::string::iterator, 6, sizeof(char) * 8>
base64_t;
typedef transform_width< binary_from_base64<std::string::iterator>, sizeof(char) * 8, 6
binary_t;
int main() { string str = "Hello, world!"; cout << str << endl; string enc(base64_t(str.begin()), base64_t(str.end())); // Problem here. It works when I specify "str.end()-1" instead of "str.end()" but I loose last character after decoding. cout << enc << endl; string dec(binary_t(enc.begin()), binary_t(enc.end())); cout << dec << endl; return 0; } Will appreciate any help. I tried std::copy as well and have same problem.
