The discussion focuses on finding a replacement for the clock() function due to its inaccurate performance under Wine on Linux systems. Users recommend using the gettimeofday() function for improved accuracy, which works well across both Win32 and Linux environments. Additionally, the Boost libraries, specifically boost::timer, are suggested as a robust alternative for timing operations with higher precision.
gettimeofday() function and its implementation in C++boost::timer for performance measurementSoftware developers, particularly those working on cross-platform applications, performance analysts, and anyone needing precise timing mechanisms in their C++ programs.
engri said:This function seems to be working incorrectly when I run my programm under wine on linux system. (program compiled with mingw32 on win32) Is there any other function that can give me more accuracy than 1 second? (i know time() is working well but i need something that changes a little bit more frequent) Yes. I know I could compile it under linux but I need it to work under Wine right now.
#include <boost/timer.hpp>
...
// Create a boost::timer object
boost::timer timerObject;
// Something you want to time goes here
// ...
// Now calculate the elapsed time
std::cout << "Elapsed time = " << timerObject.elapsed << " sec.\n";
