On: Sleep sort (2011)

[bluecalm]

C implementation for Windows:

  #include <stdio.h>
  #include <windows.h>
  #include <process.h>
  
  void sleep_on_it(void* param)
  {
      int n = *(int*)param;
      Sleep(n);
      printf("%d ", n);
  }
  
  int main(int argc, char **argv)
  {
      int ar[argc];
      HANDLE threads[argc-1];
      for (int i = 1; i < argc; i++){
          ar[i] = atoi(argv[i]);
          threads[i-1] = (HANDLE)_beginthread(&sleep_on_it, 0,  &(ar[i]));
      }
      WaitForMultipleObjects(argc-1, threads, TRUE, INFINITE);
  }

Compile with gcc -std=c99 (because of VLA's it won't work in Visual Studio).

Example:

D:>sleepsort 1000 9 2 150 1 7 17 624

1 2 7 9 17 150 624 1000
