getTickCount() for Mac and Linux?

BlitzMax Forums/BlitzMax Programming/getTickCount() for Mac and Linux?

shinkiro1(Posted 2010) [#1]
I would need a counterpart for getTickCount() for Mac/Linux.
The reason is that I want to get back a Double, not just an Int.
The Idea is to call something like getPreciseUptime:Double() which wraps the functionality for each platform.

For Linux there seems to be gettimeofday().
I found 2 functions which kind of work. The first just Returns integers like Millisecs(), the second seems more promising ...
long getTickCount()
{
 struct sysinfo si;
 if(sysinfo(&si) == 0) return si.uptime;
 return -1;
} 

int mtime()
{
    struct timeval tv;
    gettimeofday(&tv,NULL);
    return (int)(tv.tv_sec*1000 + (tv.tv_usec / 1000));
}

Would someone be able to post a version that returns a double(or float).


For OSX there is http://developer.apple.com/library/mac/#qa/qa2004/qa1398.html

However I don't have a Mac, so I'm not able to compile it and see if it works.


Hope someone is able able to help out :D
