Hi Theo,
Thanks for the reply. I will try what you suggested. But when I was trying to write external C++ code for other functionality I was facing lot of problems with it. So I would have preferred this functionality in ttcn3 itself.
But since this functionality is not available in ttcn3 I will look into that again.
Also to write an external function do we have write the header file too or it will get automatically generated?
Thank You,
Br.
Vishwanath S Bhat

Subject: Re: How to get system time
Dear Vishwanath S Bath,
two things I would like to mention here: In my understand random does not equal to uniqueness. Just because something is random this does not meant that it will not occur a second time. I think lot of scientific paper has been produced to show what a good random number generator is and what not. However uniqueness was never a criteria ;-)
Now, if you would like the feature for a unique number just use your favorite implementation and integrate it via the external function mechanism provide in TTCN-3.
So let's assume you have a library in C that does the job, just declare in your ttcn-3 script.
external function uniqueNumber() return integer;
And then implement in the PA the triExternalFunction() operation.
So you get exactly the functionality that you require.
Best regards, Theo

Hi,
Anyone knows like how to read current system time in milliseconds using ttcn3?
I want to use unique random number each time in my script. But rnd function won't guarantee the uniqueness. It may and it has generated same values. So I think to guarantee unique random number each time is to use system time.
If anyone knows how to get system time in milliseconds or has a better idea to generate a unique random number please let me know.
Thanks in advance,
Best Regards,
Vishwanath S Bhat
