...struct the result directly into tmp, eliding the temporary; and any modern C++ compiler will do so when optimizations are enabled. Of course, the bind-to-const-reference solution guarantees no-copy, so may well be preferable - but I thought it's still worth clarifying. – Pavel ...

...hing that is repeated a million times everywhere as "wisdom". "The gods of C++ gave it to us, so we have to use it." And my favorite: "It's magic." No. It's not magic. It's just an algorithm that is so simple that even a computer can run it. In my book that's pretty far from magic. My guess: You und...

...r infinite loops?, although this is WG14 document the rationale applies to C++ as well and the document refers to both WG14 and WG21: As N1509 correctly points out, the current draft essentially gives undefined behavior to infinite loops in 6.8.5p6. A major issue for doing so is that it allo...

...mitigates the risk of vendor lock-in. It's really no different with C and C++ compilers, where you have many competing offerings as well all adhering to the C++ standard. Why is Java EE library version not in sync with standard Java library releases (Java EE 6 vs. Java 7) Java EE builds on Java S...

...sh them from function calls. GCC-specific syntax. Yes, this works in C and C++. No, the function does not need to be static. The destructor runs when the shared library is unloaded, typically at program exit. So, the way the constructors and destructors work is that the shared object file contains...

... co-author to all three of these winner-algorithm papers. "Algo.27" is the C++ implementation of Fraser's skip list. Gramoli's conclusion is that's much easier to screw-up a CAS-based concurrent tree implementation than it is to screw up a similar skip list. And based on the figures, it's hard to d...

C++11 allows inline namespace s, all members of which are also automatically in the enclosing namespace . I cannot think of any useful application of this -- can somebody please give a brief, succinct example of a situation where an inline namespace is needed and where it is the most idiomatic s...

...e are sitations where gotos are important: for instance, an exception-less C++ environment. In the Silverlight source we have tens of thousands (or more) of goto statements for safe function exist through the use of macros - key media codecs and libraries often work through return values and never e...
