My recollection is that all the is_open() functions should be const, so I'm inclined to change [in]direct_streambuf. Could you give me an example of something that won't currently compile, but should?
For example this:
----- test.cpp #include <boost/iostreams/stream.hpp>
namespace io = boost::iostreams;
class empty_source { public: typedef char char_type; typedef io::source_tag category;
empty_source(int) {} std::streamsize read(char* s, std::streamsize n) { return -1; } };
int main() { io::stream<empty_source> s(0); s.is_open();
Yeah, you're right. It looks like the regression tests only cover is_open() for filtering_stream[buf]. I'll fix this, but I'm not sure if it can go into 1.33.1.
