#include <time.h>
struct tm *localtime_r(const time_t *timep, struct tm *result);

----DESCRIPTION
localtime_r 함수는 time_t type의 초단위의 시간을 지역시간(locale정보)의 struct tm type으로 변환하는 함수입니다.
localtime()함수가 변환된 결과를 local static변수에 저장하는것과 달리 localtime_r()함수는 data를 변환한 결과값을
result에 저장하기때문에 multi-thread에서도 안전한 thread-safe함수입니다.

#include <time.h>
#include <stdio.h>

struct tm *localtime_r(const time_t *timep, struct tm *result);

int main(int argc, char **argv[])
{
    time_t t;
    struct tm lt;

    if((t=time(NULL))==-1) {
        printf("time() call error\n");
        return -1;
    }
    if(localtime_r(&t, &lt)==NULL) {
        printf("localtime_r() call error\n");
        return -1;
    }
    printf("NOW TIME:%04d-%02d-%02d %02d:%02d:%02d\n",
    lt.tm_year + 1900,
    lt.tm_mon + 1,
    lt.tm_mday,
    lt.tm_hour,
    lt.tm_min,
    lt.tm_sec);

C언어로 프로그래밍을 하다보면 하나의 헤더파일이 여러 곳에서 참조될 때가 있다.

컴파일 시 해당 헤더파일이 여러번 중복되서 참조되는 상황을 막기 위해

#ifndef 와 #define이 사용된다.

예를 들어 test.h라는 헤더파일이 있다고 하자.

헤더파일의 가장 위에

#ifndef __TEST_H__

#define __TEST_H__

// 내용 작성

#define MAX_LEVEL 999

#endif

위와 같이 작성하게 되면 __TEST_H__이 상수화 되어 헤더파일 참조 시 해당 파일 참조되었으므로

한번만 참조하게 된다.

#변수가 아닌이상, 여러번 참조해도 괜찮지만, 코드의 가독성및 사이즈에 영향을 미치게 된다.
