Here's what I'd like to do: (defun work-around (arg-function) (defadvice arg-function... lindahlb

Casting from a virtual base class to a parent in a diamond inheritance? 4 144 (5/14/2007 5:41:05 PM) comp.lang.c++.moderated class a {}; class b : public a {}; class c : public a {}; class d : public virtual b, public virtual c {}; a * ptr = 0; d * ptr2 = static_cast(ptr); d * ptr3 = static_cast(st... lindahlb

Odd ostringstream::str behavior? 5 126 (10/4/2006 9:25:17 PM) comp.lang.c++.moderated The return value of ostringstream::str seems to be depednent on what the ostringstream object is constructed with (default vs. a string construction). Here's the example code demonstrating the issue #include ... lindahlb

Ambiguously ambiguous? 4 124 (10/2/2006 10:23:52 PM) comp.lang.c++.moderated I'm compiling using the g++ 3.4.3, just in case this is a compiler issue. I'm getting an odd ambiguity error that appears obviously non-ambiguous (at least to me!). struct A {}; struct B {}; struct Child_A : ... lindahlb

Dummy streams: eating std::endl? 17 76 (9/30/2006 7:38:24 AM) comp.lang.c++.moderated #include using namespace std; struct Ignore_Stream { #if 1 template Ignore_Stream operator Ignore_Stream operator & (*)(basic_ostream &)) const; #endif }; int main(int argc, char * argv[]) { Ignore_S... lindahlb

FAQ item 35.18 3 91 (7/31/2006 9:57:01 PM) comp.lang.c++.moderated "Why am I getting errors when my template-derived-class accesses something it inherited from its template-base-class?" Why is such an unfriendly behavior part of the language standard (assuming it is)? It seem... lindahlb

lower case in the STL 11 69 (12/20/2005 12:32:59 AM) comp.lang.c++.moderated I've always wondered why the standards chose to go with lower case class names in the STL. Can anyone shed some light on this decision? [ See http://www.gotw.ca/resources/clcm.htm for info about ] ... lindahlb

specialization pointer to member array 3 137 (12/2/2005 12:35:32 AM) comp.lang.c++.moderated I've got the following two functions inside a class, the second one being a specialization of the first. template class Schema { public: template void reflect(std::string const & name, T CLASS:: * pointer... lindahlb

Inline Assembly - Runtime Stack Allocation 25 30 (7/1/2004 6:44:19 AM) comp.lang.c I'm using a temporary buffer to transfer some data and would rather not allocate it on the heap. The problem is that the size of the buffer is only known upon entry into the function that utilizes it and I'd ra... lindahlb (26)

Wondering about comp.lang.c 12 28 (7/2/2004 6:48:44 AM) comp.lang.c I'm a veteran C programmer (about 20 years, including PDP11 and VAX C), and I know what is on-topic here and what is not. I write standard C everywhere possible, and encapsulate non-standard code in modules tha... severian (94)

Spatial Indexing - Event Localization - Non-locking synchronization 5 31 (8/17/2004 10:12:15 PM) comp.programming While this problem space is somewhat specific to game programming, I've posted it to other groups because the problem space can be abstractly applied to concepts in these groups (simulating worlds/systems, spat... lindahlb (26)

Non-Overlapping Spatial Indexing 2 27 (8/23/2004 6:09:09 PM) comp.programming What kinds of non-overlapping spatial index structures are out there? I know of quadtrees/octrees and their linear versions, but are there others that are more size effecient (coordinate-space compact)? I have... lindahlb (26)
