问题 Consider writing implementation for some not-so-obvious algorithm in C. For example let it be recursive quicksort, that I have found in K. N. King's "C Programming: A Modern Approach, 2nd Edition" book, that it's available from here. The most interesting part consist of two following definitions: void quicksort(int a[], int low, int high) { int middle; if (low >= high) return; middle = split(a, low, high); quicksort(a, low, middle - 1); quicksort(a, middle + 1, high); } int split(int a[], int

I already found out with another question that Windows/MingW doesn't provide the nanosleep() and setitimer() alternatives to the obsolete usleep(). But my goal is to fix all warnings that cppcheck gives me, including the usleep() style warnings. So, is there a workaround to somehow avoid usleep() on Windows without using cygwin or installing loads of new dependencies/libraries? Thanks. usleep() works with microseconds. In windows for getting microsecond precesion you should use QueryPerformanceCounter() winapi function. Here you can find how get that precesion using it. I used this code from
