GCC warnings for comma operator 18 12 (4/10/2013 11:07:14 PM) comp.lang.c Recently I wrote a macro to set a bit field at an arbitrary location in an = array of some unsigned integral type. (Can't show it because it's propriet= ary.) The bit field is specified as a bit offset from... W

Implementation of language features 27 18 (3/11/2013 10:39:52 PM) comp.lang.c++ Is there a reference (besides the ARM and hopefully consisting of WWW page(= s).) that outlines possible implementations (that is, generated object code= ) of C++ features? Something to point an experience C... W

Member vs. non-member operator overload disambiguation 3 36 (11/29/2012 10:33:26 PM) comp.lang.c++ Suppose an operator invocation matches a free-standing operator and a member operator of the class of the first argument equally well. Is this ambiguous? Or, does the Standard give member operators higher or ... W

Proposal for restricted argument-dependent name lookup 0 34 (11/24/2012 11:51:14 PM) comp.lang.c++ An access level specifier would be permitted after the "friend" keyword. T= he default would be "private" for backwards compatibility. If the sequence= "explicit friend;" appeared in a class declaration, o... W

Alternative approach to bitfields #2 3 61 (7/23/2012 2:28:09 AM) comp.lang.c The idea is to define the bitfields using a "map" structure of arrays of char, with each char corresponding to a bit in an unsigned integer. Here is some example code: /* Notes ** 1. parameters to these m... W

table generation with recursive templates 2 45 (4/30/2009 6:49:13 PM) comp.lang.c++ I wrote this code to generate an intialized array of 256 32-bit words: typedef unsigned char u_int8; typedef unsigned long u_int32; template struct TG { typedef TG Sub_start1; typedef TG Sub_start2... W

Singletons / classes with only one member 10 27 (2/27/2009 8:30:50 PM) comp.lang.c++ Suppose you have a class that has only one instance, and there is little reason to think it would ever make sense for the class to have more than one instance. What are some criteria for deciding whether it sh... W

bitset<32> and bitset<64> efficiency 20 29 (11/28/2012 8:58:59 AM) comp.lang.c++ Hi, I would like to know whether using bitset for bit operations on a 32bit machine would generally be as efficient as using a 32bit int. Moreover, if the answer is yes would it also hold for bitset and 64... narinder.claire1 (29)

pointers to member functions - can they point to operators ? 3 41 (12/1/2012 11:03:42 PM) comp.lang.c++ Hi Is is possible to set a pointers to member function to point to an operator - implemented as a class member obviously. I suppose this hinges on whether the address operator can be applied to a class membe... stephen.howe (21)

Does pure, standard C++ alone serve any practical purpose? 9 23 (12/23/2012 8:13:39 PM) comp.lang.c++ Just wondering. Are there any branches of programming industry where very good knowledge of C++ and ONLY C++ suffices or is the language alone, without the aid of external frameworks completely useless unles... pilarp (10)

Should you perform complex tasks in the constructor? 23 23 (1/10/2013 9:54:21 PM) comp.lang.c++ I've seen various arguments against this primarily centring on the fact that the only way to return errors in a constructor is to throw an exception. Of course exceptions seem to be a somewhat controversial... chicken (50)
