Pointers and Portability 2 30 (9/16/2009 4:32:44 PM) comp.lang.c Given that the standard guarantees that all pointers to struct are the same size and representation, and that the same is true for all function pointers, is this snippet of (contrived) code portable? typedef s... REH

Volatile and code reordering 2 27 (3/20/2009 3:24:19 PM) comp.lang.c I believe the consensus of this group is that volatile does not protect against code reordering. But I am not convinced. The standard says that "accesses to volatile objects are evaluated strictly according to ... REH

std namespace #2 13 30 (2/6/2009 2:28:20 PM) comp.lang.c++ This is probably a dumb question, but... I have a code file in which I cannot use a using directive to pull in std (because it conflicts with a library I have to pull in). So, how to I handle names that can be... REH

volatile vs volatile_components 4 32 (11/5/2008 3:00:01 PM) comp.lang.ada Is there a difference between defining an array with pragma volatile vs volatile_components? The standard says that if the object is volatile, its components are volatile. So, if the object is defined as having... REH

conversion syntax 23 25 (10/8/2008 2:29:57 PM) comp.lang.c++ It it permissible to use the constructor style cast with primitives such as "unsigned long"? One of my compilers accepts this syntax, the other does not. The failing one chokes on the fact that the type is not ... REH

set of pointers 17 29 (2/26/2008 3:31:53 PM) comp.lang.c++ Is it well defined to use a std::set of pointers? I ask because of the restrictions on using relational operators with pointers. Does a set of pointers suffer from the same restrictions, or does the standard ... REH

Compiler Bug 12 30 (12/4/2007 9:58:06 PM) comp.lang.ada I have an issue that my compiler vendor is trying to tell me is not a bug. I have two functions. They both have a local variable of the same name. One calls the other (which is inlined). The compiler treats... REH

object lifetime 4 42 (7/19/2007 4:02:42 PM) comp.lang.c++ I've been trying to better understand the subtle rules for object lifetime. The standard says that pointers to the memory of a dynamically allocated object may be used in limited ways after the object's destru... REH

Placement new and explicit destruction 8 21 (7/16/2007 9:32:09 PM) comp.lang.c++ This curiosity popped into my head on the way to work today. I wouldn't actually do this, but just wondering. Is the following defined behavior? #include class T { }; int main() { T* p = new T(); ... REH

protected member #2 6 25 (5/19/2007 2:32:12 PM) comp.lang.c++ Can someone please tell me what is wrong with this snippet of code? GCC is telling me that "foo2 is protected within this context" (that I cannot use it with BBB). class AAA { protected: virtual int foo2... REH

Objective C blocks 34 41 (9/10/2009 6:33:58 PM) comp.lang.c Have you guys checked this out? http://arstechnica.com/apple/reviews/2009/08/mac-os-x-10-6.ars/10 It describes a change to Objective C made by Apple to support anonymous functions in C. The syntax is actuall... beej (444)

fpurge/fflush 27 35 (9/15/2009 3:23:57 PM) comp.lang.c i use gcc in ubuntu. My problem is that, when i use getchar() twice to read a single character each time, it doesn't stop up and asks for a new character at second time. The two codes i use(fflush/fpurge) is: ... anders.refslund (9)

Change in C 67 32 (9/16/2009 11:27:10 PM) comp.lang.c In the thread "When will C have an object model?", I found a message from Mr Heathfield that warrants a deeper discussion. That thread was (for a change) an interesting one. Richard Heathfield a �crit : > >... jacob24 (973)

single producer, single consumer 41 42 (10/6/2009 2:00:23 PM) comp.lang.c++ Here is some code I came up with for a lock free single producer single consumer algorithm. I have done some tests using GCC with -O3 optimizations and all seems well. I would like some constructive criticism... goodfella005 (16)

signal handling and (structured) exception handling 36 36 (10/9/2009 12:18:39 AM) comp.lang.c++ I'm a little bit at loss, why the new C++ standard (C++0x) does not include something like Windows structured exception handling. I certainly prefer a C++ Exception to a signal, as the signal only gives you the... ExcessPhase (36)

subroutine stack and C machine model 128 41 (10/12/2009 2:13:47 AM) comp.lang.c I'm looking and talking about a lot of C that is new to me this weekend. Does the abstract machine that is described in the standard have a subroutine stack? I've heard before that one can imagine things as a... merrill (193)

why gcc can not recognize ^M 4 51 (10/20/2009 4:18:50 PM) comp.lang.c why gcc can not recognize ^M? but cc of SunOS 5.8 can accept it without error . -bash-3.00$ gcc a.c -o a a.c: In function 'main': a.c:4: error: missing terminating " character a.c:5: error: missing terminating... zhangyefei.yefei (11)

Beginner's guide to MinGW? 60 187 (3/9/2010 9:51:53 PM) comp.lang.c Folks, I know this isn't a C-language related question, but before I get into C, I have to have a compiler. In fact, I have been using DJGPP for many years, but I have recently upgraded to a 64-bit CPU... MikeC

Help reading performance counters 2 35 (4/5/2010 1:15:26 PM) comp.os.vxworks Hello, Does any body have any information on how to read performance monitoring counters for the intel processors in vxworks. I found out from the architecture supplement that we can use the functions pentiumP... dakshina.dasari (11)
