Only if your to-decimal function operates specifically on 33 bit values. Printf would not print a negative number unless it saw 1111111111111111111111111111111111111111111111111111000111111010 I think the point is that something is sign-extending to 64 bits, and it seems wrong to sign-extend a timestamp which wraps. Especially wrong that only one number in the sequence was sign-extended. -- Michael Conrad IntelliTree Solutions llc. 513-552-6362 [EMAIL PROTECTED] _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
