[-- Attachment #1 --] Hi there, I am trying to read the on board Pentium Time Stamp Counter. Is there an API in Unix that allows me to read it directly? Or some assembly language line that I can drop into my code? I need the high speed counters to profile some code. I don't want to use the classical time API that is provided in <time.h> -Hao [-- Attachment #2 --] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"> <HTML> <HEAD> <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1"> <META NAME="Generator" CONTENT="MS Exchange Server version 5.5.2652.35"> <TITLE>high speed timestamp counter</TITLE> </HEAD> <BODY> <P><FONT SIZE=2 FACE="Arial">Hi there,</FONT> </P> <P><FONT SIZE=2 FACE="Arial">I am trying to read the on board Pentium Time Stamp Counter.
