HI,
RTOS SDK V1.2.0
代码中使用下面的函数,在编译的时候提示 没有定义。该怎么处理?
clock_t _EXFUN(clock, (void));
double _EXFUN(difftime, (time_t _time2, time_t _time1));
time_t _EXFUN(mktime, (struct tm *_timeptr));
time_t _EXFUN(time, (time_t *_timer));
#ifndef _REENT_ONLY
char *_EXFUN(asctime, (const struct tm *_tblock));
char *_EXFUN(ctime, (const time_t *_time));
struct tm *_EXFUN(gmtime, (const time_t *_timer));
struct tm *_EXFUN(localtime,(const time_t *_timer));
#endif
size_t _EXFUN(strftime, (char *_s, size_t _maxsize, const char *_fmt, const struct tm *_t));
char *_EXFUN(asctime_r, (const struct tm *, char *));
char *_EXFUN(ctime_r, (const time_t *, char *));
struct tm *_EXFUN(gmtime_r, (const time_t *, struct tm *));
struct tm *_EXFUN(localtime_r, (const time_t *, struct tm *));
