三个模式传输的问题，请高手指教（上）

[chengpeng820921]

求救，请大虾帮帮小弟，小弟这个程序老是得不到我要的结果，
这个程序的功能是看三个模式下文件的传输速度。source,source_1...source_9
这几个文件要自已建，自己任意用一个文件改名即可。源代码如下
#include<iostream.h>
#include<windows.h>
void filter_nobuffer(char *source,char *sink,void(*func)(char *addr));
void filter_sequen(char *source,char *sink,void(*func)(char *addr));
void filter_overlp(char *source,char *sink,void(*func)(char *addr));

void f1(char *addr);
void f2(char *addr);
void f3(char *addr);
void f4(char *addr);
void f5(char *addr);

#define BUFFER_SIZE 1024
char *buffer;

void main()
{buffer=new char[BUFFER_SIZE];

DWORD tick;

DWORD nobuffer_average_time=0;
DWORD sequen_average_time=0;
DWORD overlp_average_time=0;

cout<<"无文件高速缓存模式正在运行..."<<endl;
DWORD nobuffer_start_time=GetTickCount();
DWORD nobuffer_end_time=GetTickCount();

tick=nobuffer_start_time;
filter_nobuffer("source.txt","nobuffer_1.txt",f1);
cout<<"nobuffer 0-1:"<<GetTickCount() - tick<<"ms."<<endl;

tick=GetTickCount();
filter_nobuffer("source_1.txt","nobuffer_2.txt",f2);
cout<<"nobuffer 1-2:"<<GetTickCount() - tick<<"ms."<<endl;

tick=GetTickCount();
filter_nobuffer("source_2.txt","nobuffer_3.txt",f3);
cout<<"nobuffer 2-3:"<<GetTickCount() - tick<<"ms."<<endl;

tick=GetTickCount();
filter_nobuffer("source_3.txt","nobuffer_4.txt",f4);
