numeric::interval::abs() bug
by Terry Golubiewski 02 Aug '06

02 Aug '06

The following code does not compile with g++ nor MSVC 2003 because of ambiguity of first argument to std::max() in numeric::abs(). Is a typecast needed in interval/utility.hpp? terry #include <boost/numeric/interval.hpp> #include <iostream> typedef boost::numeric::interval<short> Interval; std::ostream& operator<<(std::ostream& os, const Interval& x) { return os << x.lower() << ".." << x.upper(); } int main() { Interval r1(-3, 7); std::cout << "r1=" << r1 << std::endl; Interval r2 = boost::numeric::abs(r1); std::cout << "r2=" << r2 << std::endl; return 0; } // main

bind/lambda/phoenix and result_of
by David Abrahams 02 Aug '06

02 Aug '06

One happy day, we'll have auto and decltype... Until then, we have no reasonable way to declare the type of bind expressions. So I got to thinking, maybe something like this could be made to work: result_of<bind_(std::minus<int>, int, _1_)>::type f = bind(std::minus<int>(), 3, _1); For lambda, I guess we could do something like this: result_of<minus_(int, _1_)>::type f = 3 - _1; Does this direction make sense? -- Dave Abrahams Boost Consulting www.boost-consulting.com

AMDG Daniel, >> The only case I can think of that won't work is the unnumbered forms of >> binary operators. > > > Can you provide an example? > Regards, Daniel Sure. template<class Base> struct X : boost::addable<X, Base> { ... }; Boost.Operators does not recognize Base. Therefore, (as I understand the library) it will think I mean boost::addable2<X, Base> instead of boost::addable1<X, Base> In Christ, Steven Watanabe

Getting a xsd:datetime from boost::date_time
by Joe Van Dyk 02 Aug '06

02 Aug '06

Hi, (sorry if this is off topic) I need to get the current date and time and convert it into a string that follows the xsd:datetime time stamp format: [-]CCYY-MM-DDThh:mm:ss[Z|(+|-)hh:mm]. (timezone should be UTC) Any ideas on how to do that? The Boost::Date_Time library documentation is confusing to my feeble mind. Thanks, Joe

[Boost-bugs] [ boost-Bugs-1532684 ] Changing size of memory-mapped file on Windows

Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Changing size of memory-mapped file on Windows Initial Comment: My email address is barrywhart(a)yahoo.com. There is a bug in mapped_file_source::open_impl(mapped_file_params p) This function does not correctly check for errors from SetFilePointer, as documented in the MSDN page below. (See "Case Two: calling the function with lpDistanceToMoveHigh != NULL") http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/… Current code: ::SetFilePointer(pimpl_->handle_, sizelow, &sizehigh, FILE_BEGIN); if (::GetLastError() != NO_ERROR || !::SetEndOfFile(pimpl_->handle_)) detail::cleanup_and_throw(*pimpl_, "failed setting file size"); Should be: DWORD dwResult = ::SetFilePointer(pimpl_->handle_, sizelow, &sizehigh, FILE_BEGIN); if (dwResult == INVALID_SET_FILE_POINTER ::GetLastError() != NO_ERROR || !::SetEndOfFile(pimpl_->handle_)) detail::cleanup_and_throw(*pimpl_, "failed setting file size"); -- Even after this fix, the ability to resize an existing file is not really useful because the file is apparently recreated rather than resized. I am working around this by resizing the file using system calls, but I wonder if this is how the function is supposed to work?! ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1532684&group_… ------------------------------------------------------------------------- Take Surveys.

Yes this is what I meant. It seems that there is different nomenclature regarding this relatively common concept. Is that your library you pointed to above? Sohail
