More important would be to do this before tagging a version and creating a file release. - -- /* Matt BrookingsGnuPG Key D9414F70 Software developer Systems technician Inter7 Internet Technologies, Inc.

I am planning to use GMP GNU Multiple Precision Arithmentic Library. It claims to be the fastest bignum library on planet. GMP is a free library/ There is no practical limit to the precision except the ones implied by the available memory in the machine. GMP has a rich set of functions to help you deal with these large numbers. http://gmplib.org At this point, I am not sure if bignum is an overkill, but I will be trying this soon and will keep you folks posted Regards Manvendra (http://www.indimail.org) !DSPAM:4978452a32681009520127!

Pretty much every response in regards to my question has shown me this. > All programs that deal with the quota (maildirsize file) will have to > use 128-bit numbers (long long?) or whatever new method you come up > with.

Maybe they can use a > dynamically linked library? Where do you come up with 128bit from? On most systems a 'long long' is going to be a 64bit integer. That's what I'm currently using. - -- /* Matt BrookingsGnuPG Key D9414F70 Software developer Systems technician Inter7 Internet Technologies, Inc.
