Question

win7系统Visual Studio中VC++程序“无法打开源文件sys/resource.h”

# include<stdio.h>
#include <sys/timeb.h>
#include <sys/types.h>
#include <sys/resource.h>
#include "mytimer.h"

mytimer *mytimer_create(void)
{
mytimer *pTimer;

pTimer=(mytimer *)malloc(sizeof(mytimer));
pTimer->abs_stTime=0;
pTimer->state=MYTIMER_STATE_STOP;

return pTimer;
}

double mytimer_get_abs(void)
{
struct timeval tp;
struct timezone tz;
int ret;

ret=gettimeofday(&tp,&tz);
if(ret!=0)
return -1.0;

return (double)tp.tv_sec+(double)tp.tv_usec/1e6;
}

int mytimer_start(mytimer *pTimer)
{
double abs_time;

abs_time=mytimer_get_abs();
if(abs_time<0.0)
return -1;

pTimer->abs_stTime=abs_time;

return 0;
}

double mytimer_hold(mytimer *pTimer,int index)
{
double abs_time;

abs_time=mytimer_get_abs();
if(abs_time<0.0)
return -1;

pTimer->abs_hldTime[index]=abs_time;

return 0;
}

double mytimer_stop(mytimer *pTimer)
{
double abs_time;

abs_time=mytimer_get_abs();
if(abs_time<0.0)
return -1;

pTimer->abs_curTime=abs_time;

return 0;
}

double mytimer_get_hold(mytimer *pTimer,int index)
{
return pTimer->abs_hldTime[index]-pTimer->abs_stTime;
}

double mytimer_get_curr(mytimer *pTimer)
{
return pTimer->abs_curTime-pTimer->abs_stTime;
}

void mytimer_free(mytimer *pTimer)
{
free(pTimer);
return;
}

说明工程里这个文件不存在.

追问

windows系统里有哪个文件可以替换这个文件

追答

要有源工程目录 工程中单一的文件无法执行
