target exec, gdb, gfortran
|
| |
I thought I would ask a question that is decidedly non-political, although I will admit that a frenchman made my fourth. As well as infinite cheeseburgers, and, of course, jenny. When I believe to be issuing commands to dos that will step me through gdb, I receive counter-communication that talks of target exec.... more »

struct with const string
|
| |
Hello, Looking for a solution to take something like: const TCHAR StrArrayZ[]=_T("Item1\0Item2\0 Item3\0"); and convert it to something like: ...struct { union { const TCHAR StrArrayZ[1]; struct { const TCHAR I1[]=_T("Item1"); const TCHAR I2[]=_T("Item2"); const TCHAR I3[]=_T("Item3");... more »

What am I doing wrong?
|
| |
I think I know what the problem is. I'm passing an array to strdup() which is not what it wants and is producing a bus error. But, even knowing the cause of the problem I'm having difficulties thinking of a suitable solution. I'm basically reading a CSV file and then tokenising it to get the relevant values in a useable form. So I need to read the file one line... more »

frand
|
| |
When porting a program to MS-Windows I got a redefinition error on "frand" (already defined in stdlib.h). Is it legal if I use "frand" in a source file if stlib.h is not included there?

Understanding char **argv
|
| |
Hello all, Forgive the somewhat simple question I am sure this will be, but I am having some problem understanding what: char **argv looks like. For instance, i know through trial and error that if I do this: ...int main(int argc, char *argv[]) { int l; for( l=0; l<argc; l++ ) {... more »

Sandbox server
|
| |
How would one program a sandbox? Let's say the server and all clients have the same architecture, and environment (for example 32bit x86-Linux environment). The server shall offer sandbox services to clients. A remote client can get a sandbox (an empty directory space) on the server, upload his precompiled executable program,... more »

information hiding vs. inlining
|
| |
Do compilers inline functions even if the programmer could not do it manually because the needed information is hidden at the language level? I am talking about stuff like incomplete types and static variables e.g. .. get_attribute(object); .. Where object is an incomplete type in this unit and get_attribute basically... more »
