To expand on the previous solution, if you want to then get the window names:

// get window Id:
Window w = (Window) array[k];

char* name = '\0';
status = XFetchName(display, w, &name);
if (status >= Success)
{
    if (name == NULL)
        printf("Found: %ul  NULL\n", w);
    else
        printf("Found: %ul  %s\n", w, name);
}
XFree(name);
