_ftime

_ftime是一種函式，功能是返回當前時間。

基本介紹

• 外文名：_ftime
• 類型：函式
• 函式原型：void _ftime(
• 學科：程式設計

函式簡介

函式原型：

void _ftime(

struct _timeb *timeptr

);

頭檔案：

<sys/types.h> and <sys/timeb.h>

函式功能：

返回當前時間

參數說明：

struct _timeb {

time_t time;

unsigned short millitm;

short timezone;

short dstflag;

};

結構體定義於<sys/timeb.h>下

相關函式：

void _ftime32(

struct __timeb32 *timeptr

);

void _ftime64(

struct __timeb64 *timeptr

);

程式示例

#include <stdio.h>

#include <sys/timeb.h>

#include <time.h>

int main( void )

{

struct _timeb timebuffer;

char timeline[26];

errno_t err;

time_t time1;

unsigned short millitm1;

short timezone1;

short dstflag1;

_ftime( &timebuffer ); // C4996

// Note: _ftime is deprecated; consider using _ftime_s instead

time1 = timebuffer.time;

millitm1 = timebuffer.millitm;

timezone1 = timebuffer.timezone;

dstflag1 = timebuffer.dstflag;

printf( "Seconds since midnight, January 1, 1970 (UTC): %I64d\n",

time1);

printf( "Milliseconds: %d\n", millitm1);

printf( "Minutes between UTC and local time: %d\n", timezone1);

printf( "Daylight savings time flag (1 means Daylight time is in "

"effect): %d\n", dstflag1);
