Taking address of struct temporary 5 58 (7/19/2012 1:58:30 AM) comp.lang.c I've been playing around with an object library and have run into an inconsistency between using it under a C compiler and using it under a C++ compiler. I wanted a way to declare "objects" statically, mea... nroberts

Function casting - UB? 21 53 (6/27/2012 3:50:23 PM) comp.lang.c In C++ this would be totally undefined. How about in C? It works on my machine with my compiler... If it's UB, is it one of those rules that pretty much has to work anyway? What I mean is things like th... nroberts

Terminology - RAII vs. Scope Guard vs...? 28 44 (4/10/2012 8:47:51 PM) comp.lang.c++ So RAII is when you make it so that the acquisition of a resource is tied to the initialization of a scope-based variable that cleans up said resource when it's destroyed. A Scope Guard is something you set up... Noah

Array sizes in function parameters. 4 43 (2/25/2012 1:08:23 AM) comp.lang.c Say I do this: void fun(char buffer[2048]) ... and then assume that any buffer I'm passed in will have 2048 bytes. That's silly, right? At least with gcc I can pass in any size array there. Pretty sure I r... nroberts

strncpy and 'n' 45 52 (2/16/2012 5:05:07 PM) comp.lang.c Consider: char const* f(char const* incoming) { static char buf[MAX]; strncpy(buf, incoming, strlen(incoming)); } Is there ANY reason to use strncpy like that? I'm working on a project that has such use... nroberts

a = b or memset/cpy? 18 51 (2/7/2012 5:02:06 PM) comp.lang.c memset and memcpy are turning up in profiles a lot. I'd like to speed things up a bit. Sometimes it is clear that using = to initialize a local would be better than memset. I might not gain anything, but at ... nroberts

Am I being too C++ like? 86 53 (1/18/2012 9:53:57 PM) comp.lang.c I'm working on a C project and I come from C++ background. I used to work with C 10 years ago though when I was first learning various languages and used things like Xlib, Xt, etc... I keep getting told that ... nroberts

unit test logging? 1 45 (12/19/2011 6:23:35 PM) comp.programming Should object logging be included in unit tests? We do expect that when event X happens we log to log Y at level Z, but is this too much? ... nroberts

Odd error I can't seem to recreate 13 45 (11/4/2011 6:52:56 PM) comp.lang.c++ In a significant code base I'm running into this problem: This works: test_service service; std::string result =3D job->run_query(service); This does not.: std::string result =3D job->run_query(test_service()... Noah

Template overriding base class virtual function? 3 76 (7/24/2012 1:26:40 PM) comp.lang.c++ I'm trying to write something like a clone() method using the curiously recurring template pattern.
