解决方法: In my case, I runconda upgrade -c conda-forge --allto have access to all packages via the conda-forge channel. It immediately solves my problem! 请参考: https://root-forum.cern.ch/t/error-timespec-get-has-not-been-declared-with-conda-root-package/45712/8

int timespec_getres( struct timespec *ts, int base ); (since C23) If ts is non-null and base is supported by timespec_get, modifies *ts to hold the resolution of time provided by timespec_get for base. For each supported base, multiple calls to timespec_getres during the same progra...

1、时间类型。Linux下常用的时间类型有4个:time_t,struct timeval,struct timespec,struct tm。 (1)time_t是一个长整型,一般用来表示用1970年以来的秒数。 (2)Struct timeval有两个成员,一个是秒,一个是微妙。 struct timeval { longtv_sec;/*seconds*/ ...
TIMESPEC_TO_TIMEVAL(struct timespec*p1,struct timeval*result); 如果系统的头文件中找不到,也可以自己实现下,明白这两个结构的细节结构,实现也很简单,这里拿timeradd举例,其它不说了。 #define timeradd(tvp, uvp, vvp) \ do { \ (vvp)->tv_sec=(tvp)->tv_sec+(uvp)->tv_sec; \ ...
int clock_gettime(clockid_t clk_id, struct timespec *tp); 获取时间戳,精度达到纳秒,时间存储结构体如下: struct timespec { time_t tv_sec; /* seconds */ long tv_nsec; /* nanoseconds */ }; 参数clk_id有很多种取值,常见的有:CLOCK_REALTIME(系统时间,受系统时间调整影响,所以不保证是递增),CL...
