[asio] no error or exception sent ?
by Mathieu Peyréga 01 Oct '09

01 Oct '09

Hello, i'm using a tcp socket from asio 1.40 framework and i have the following behaviour : i establish a connection to a server and start receiving data i now want my software to be robust to server deconnexion/reset so i simulate it by shuting down the server equipment (which is an external hardware equipement) i would expect such operation to interrupt any pending async_read_some operation with an error code, but it doesn't is there some way to have the expected behaviour ? regards, Mathieu

spurious string
by Surya Kiran Gullapalli 01 Oct '09

01 Oct '09

Hello all, I'm reading an html file and parsing data from it. I've encountered a spurious string (researcherâ€™s). Notepad++ shows that string as *researcher's *. I'm reading the file using std::fstream class. Is there any way i can read the string and get the spurious characters replaced using boost string/regex algorithms ? Thanks, Surya

[boost.datetime] Formating dates as strings
by Sean Farrow 01 Oct '09

01 Oct '09

Hi: What is the best way to format a date in a specific way. For example I have a client who wants there dates formatted as 01/10/2009, and another who wants Thursday 01 October. These need to be output as std::wstrings. Any help appreciated. Sean.

How to install boost 1_39 on itanium server
by manish4gupta 01 Oct '09

01 Oct '09

I am installing the boost on itanium (64 bit red hat) machine. I am following the three steps. ./bootstrap.sh --prefix=/usr/local ./bjam ./bjam install After installation, libboost files are all located in /usr/lib. But i am trying to run one simple code. #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/interprocess/allocators/allocator.hpp> #include <boost/interprocess/containers/map.hpp> #include <boost/interprocess/containers/string.hpp> #include <iostream> using namespace boost::interprocess; //Typedefs of allocators and containers typedef managed_shared_memory::segment_manager segment_manager_t; typedef allocator<void, segment_manager_t> void_allocator; typedef allocator<char, segment_manager_t> char_allocator; typedef basic_string<char, std::char_traits<char>, char_allocator> char_string; //Definition of the map holding a string as key and complex_data as mapped type typedef std:air<const char_string, int> map_value_type; typedef allocator<map_value_type, segment_manager_t> map_value_type_allocator; typedef map< char_string, int, std::less<char_string>, map_value_type_allocator> complex_map_type; int main () { shared_memory_object::remove("MySharedMemory"); //Create shared memory managed_shared_memory segment(create_only,"MySharedMemory", 65536); //An allocator convertible to any allocator<T, segment_manager_t> type void_allocator alloc_inst (segment.get_segment_manager()); //Construct the shared memory map and fill it complex_map_type *mymap = segment.construct<complex_map_type>("MyMap")(std:: less<char_string>(), alloc_inst); char_string cs("test", alloc_inst); for(int i = 0; i < 100; ++i) { mymap->insert(std:air<char_string, int>(cs , i)); } return 0; } with command g++ program_name.cpp -lrt It is showing error "No such file and directory" for every header file.

asio - failed to compile "chat_client.cpp" example on Cygwin
by Steve Ong 30 Sep '09

Hi, I downloaded the "chat_client.cpp" from the boost website (http://www.boost.org/doc/libs/1_37_0/doc/html/boost_asio/examples.html) and try to compile it on Cygwin (see my compile statement below..), but it failed.

[serialization] Support for boost classes
by Chard 30 Sep '09

30 Sep '09

Is there a particular reason why the serialization library does not provide serialization functions for types in other boost libraries? Unless I've missed them, but I find I've had to provide implementations for, e.g.: boost::filesystem::path - trivial. boost::multi_array - also seems straightforward, unless I'm missing something there. They don't require invasive techniques, so is it that it's being left up to the particular library owners to decide whether or not to support serialization? If it's an efficiency argument, e.g. one size doesn't fit all, I don't see why 'an' implementation could not be provided (perhaps in /serialization/boost/xyz.hpp). After all, no one would be forced to include/use that particular implementation.

Using Boost.asio with IGMPv3
by Steve T 30 Sep '09

30 Sep '09

Greetings, I am currently using Boost.asio to send and receive UDP multicast messages. I now have the requirement that all UDP messages use IGMPv3. Is IGMPv3 supported using the Boost.asio library? If not, how can I implement IGMPv3 in Boost.asio? It seems that adding IGMPv3 could be implemented by adding the IP_ADD_SOURCE_MEMBERSHIP option. What would be the best method for adding the socket option IP_ADD_SOURCE_MEMBERSHIP? Thanks in advance, Steve

[Boost.MPL]is it possible to generate types with all combinations of template arguments?
by Tan, Tom (Shanghai) 30 Sep '09

30 Sep '09

I have a templated class template<class U, class V, class W> class S { //... implementations }; and some stock type implementations for type U, V and W: typedef boost::mpl::vector<U0, U1> u_types; typedef boost::mpl::vector<V0, V1, V2, V3, V4> u_types; typedef boost::mpl::vector<W0, W1, W2, W3, W4> w_types; I want to test class S with all possible combinations of the template arguments, typedef boost::mpl::vector< S<U0,V0,W0>, S<U0,V0,W1>, // ... S<U1,V4,W4>, > s_types; like this: boost::mpl::for_each<s_types>(test_func). The only problem is there are 2*5*5 = 50 combinations that I do not wish to type in one by one. Is there a way to generate all the combinations with boost::mpl or Boost.Preprocessor? thanks.
