Hello, All!
This code:
#include <fstream>
#include
#include
#include
#include
#include
int main(int argc, char* argv[])
{
{
char testdata[4] = "asd";
std::ofstream os("test.txt", std::ios::binary);
boost::archive::polymorphic_binary_oarchive ar(os);
// boost::archive::polymorphic_text_oarchive ar(os);
// boost::archive::text_oarchive ar(os);
// boost::archive::binary_oarchive ar(os);
ar & boost::serialization::make_binary_object(&testdata,
sizeof(testdata));
assert(os.good());
}
{
char testdata[4] = " ";
std::ifstream is("test.txt", std::ios::binary);
assert(is.good());
boost::archive::polymorphic_binary_iarchive ar(is);
// boost::archive::polymorphic_text_iarchive ar(is);
// boost::archive::text_iarchive ar(is);
// boost::archive::binary_iarchive ar(is);
ar & boost::serialization::make_binary_object(&testdata,
sizeof(testdata));
assert(is.good());
assert(testdata[0] == 'a');
}
return 0;
}
does not work as expected - last assert failed. With
text_iarchive/text_oarchive or binary_iarchive/binary_oarchive everything
works fine. With polymorphic_text_archive another assert failed - is.good()
returns false. I'm using VC 7.1 compiler. I had trying to compile this code
with Intel 8.1 compiler but got errors, identical for polymorphic binary and
text archives :
