winapi - How to call a kernel32.dll function GetTickCount() using LoadLibrary(..) in C++ -


i searching function time in milliseconds on windows machine. essentially, want call winapi function gettickcount(), i'm stuck on "use loadlibrary(...) n call gettickcount() function" part..

i searched every forum n googled everywhere people have used incomplete codes don't compile..can write short sample program load kernel32.dll , call gettickcount() display time in milliseconds?

please write code compiles!

you can't load kernel32.dll, it's loaded every process. , gettickcount exists on every version of windows, don't need getprocaddress see if exists. need is:

#include <windows.h> #include <iostream>  int main(void) {     std::cout << gettickcount() << std::endl; }

a dynamic load example (since winmm.dll not preloaded):

#include <windows.h> #include <iostream>  int main(void) {     hmodule winmmdll = loadlibrarya("winmm.dll");      if (!winmmdll) {         std::cerr << "loadlibrary failed." << std::endl;         return 1;     }      typedef dword (winapi *timegettime_fn)(void);     timegettime_fn pfntimegettime = (timegettime_fn)getprocaddress(winmmdll, "timegettime");      if (!pfntimegettime) {         std::cerr << "getprocaddress failed." << std::endl;         return 2;     }      std::cout << (*pfntimegettime)() << std::endl;     return 0; }

i've compiled , run example using visual studio 2010 command prompt, no special compiler or linker options needed.
