Question

I am trying to get time with microseconds through glib which will work on windows too, if possible.

My approach:

     char buff[256];
     GTimeVal mtime;
     g_get_current_time(&mtime);
     strftime(buff, sizeof(buff), "%Y-%m-%d %H:%M:%S.%%06u", mtime);
     printf("%s\n", buff);

… don’t work as expected.

What to do to get this working?

Thanks.

[Edit]
Second example:

GTimeVal start, finish;
g_get_current_time(&start);

//some operation

g_get_current_time(&finish);

GTimeVal el;
el.tv_sec = finish.tv_sec - start.tv_sec;
el.tv_usec = finish.tv_usec - start.tv_usec;
if (el.tv_usec < 0)
{
    el.tv_usec += 1000000;
    el.tv_sec--;
}

char st[24] = {0};
char qt[32] = {0};
if (counter)
{
    sprintf(st, "%s%d%s", "   Finded ", counter, " results");
    sprintf(qt, " %u.%06u %s", (guint)el.tv_sec, (guint)el.tv_usec, " sec");
}

Your best shot for portability may be to drop GTimeVal, which is deprecated in glib, for GDateTime and related functions. (g_date_time_format() in place of strftime(), g_date_time_new_now() in place of g_get_current_time()).
