Q: Timer with <sec resolution

[Jo. Schmitt]

Hi all!

Each time an event happens I want to print a timestamp.
Using 'time_t' etc. works fine but it only has attributes for
an 'one second resolution'.

I tried to examine the code of Tcp-/Windump because
they have a 0.000000 second resolution. Unfortunatly I
dont really understand the code there. Could only
figure out that a 'timeval' struct from the BSD/time.h
file has been used. (which I do not have an could not download
from the www (maybe its not free anyway)

How are you programming timers with an sec.000 resolution??
A ms resulution would be fine for me

Shouldn't there be something other than 0 in there?

I don't believe there is a standard, portable way of doing this. Try a
platform-specific newsgroup. It looks like you might be using FreeBSD,
so help shouldn't be hard to find.

Good luck,

Well, I use QueryPerformanceCounter(), but that only works in Win32.

You can try to use Sword C++ Library.
Its "sword::Time" class has a millisecond resolution.
And it should be portable to Window and Linux (at least).
