__rdtsc

Visual Studio 2010

Microsoft Specific

Generates the rdtsc instruction, which returns the processor time stamp. The processor time stamp records the number of clock cycles since the last reset.

Copiar 
unsigned __int64 __rdtsc();

A 64-bit unsigned integer representing a tick count.

Intrinsic

Architecture

__rdtsc

x86, x64

Header file <intrin.h>

This routine is available only as an intrinsic.

The interpretation of the TSC value in this generation of hardware differs from that in earlier versions of x64. See hardware manuals for more information.

Copiar 
// rdtsc.cpp
// processor: x86, x64
#include <stdio.h>
#include <intrin.h>

#pragma intrinsic(__rdtsc)

int main()
{
    unsigned __int64 i;
    i = __rdtsc();
    printf_s("%I64d ticks\n", i);
}
