[c++] get interval time

특정 구간(들) 을 측정하고 싶을때 사용할 수 있도록 구현 하였다.

IntervalTime.cpp

IntervalTime.h

method

template<typename T>
void StartClock(T param);

template<typename T>
double EndClock(T param, bool print = true)throw(std::exception);

param 으론 char,int,double,string 타입이 들어갈 수 있다.

구간에 이름을 붙여서 측정하는 것이 가능하다.

example

#include"IntervalTime.h"
#include<cstdio>	//intptr_t
#include<cstdlib>	//EXIT_SUCCESS
#ifdef __GNUC__
#include<unistd.h>        //usleep(nano), sleep(sec)
//usleep
void msleep(__useconds_t s) {
	usleep(s * 1000);
}
//sleep
#elif defined(_MSC_VER)
#include<Windows.h>        //Sleep(micro)
void(_stdcall *msleep)(DWORD s) = Sleep;
void sleep(DWORD s) {
	Sleep(s * 1000);
}
#endif 
void foo() {	//foo 함수에 대한 시간 측정 출력
	times::IntervalTime::StartClock(__FUNCTION__);	
	sleep(1);
	times::IntervalTime::EndClock(__FUNCTION__);
}
int main() {
	double total = 0.0;
	for (intptr_t i = 0; i < 5; i++) {
		//Whole for 에 대한 시간 측정 시작
		times::IntervalTime::StartClock("Whole for");	
		{
			// 1에 대한 시간 측정 시작
			times::IntervalTime::StartClock(1);		
			{
				sleep(1);
			}
			times::IntervalTime::StartClock(2);
			foo();
			// 1 에 대한 시간 경과 시간 출력
			times::IntervalTime::EndClock(1);			
			{
				sleep(2);
			}
			times::IntervalTime::EndClock(2);
		}
		//Whole for에 대한 경과 시간 출력 및 반환.
		total += times::IntervalTime::EndClock("Whole for");	
	}
	
	std::cout << "total time : " << total << std::endl;
	return EXIT_SUCCESS;
}

result
