I set up a test case in which I populate 15,000 rows in a table using isql and monitoring Sybase performance on SUN and LINUX boxes. I get an average performance of about 40 inserts per second on a low end 360 MHz Sun machine and an average performance of about 13 inserts per second on a 2.8 GHz...

Ping using protocol NLWNSCK. Net-Lib protocol driver call to connect 2 end points failed." This is the error message I get when I try to ping my Sybase installation on the SuSE LINUX box. I can ping using the same utility to the Sybase database installed on Solaris. So, I'm sure there is no...

I have some doubts regarding the use of fstat(). The function signature described in ..\VC98\Include\Sys\stat.h is _CRTIMP int __cdecl fstat(int, struct stat *); The confusion is that in my c++ program if I pass a local (stack) variable declared as struct stat st; int result =...

For optimized coding I use the following guideline: Inline methods that - have no loops, are non virtual, are non-recursive, are not (esp.derived) class constructors / destructors and do not make calls to virtual functions. The important point missing here is a specification on the number of...

in a method void print_mesg(const char *s) {..} // do something int main() { print_mesg(&quot;Hello&quot;); } Where is the new method to hold &quot;Hello&quot;. Also I don't need to call delete []s exclusively ? There is no memory leak here ? Why ?
