网上很多人写到,timeval结构解释错误
*
DESCRIPTION
The functions gettimeofday and settimeofday can get and set the time as
well as a timezone. The tv argument is a timeval struct, as specified
in <sys/time.h>:
struct timeval {
time_t tv_sec; /* seconds */
suseconds_t tv_usec; /* microseconds */
};
我很无语,只能说写这话的人英语很水,microsecond 是微秒的意思,简写为usec
毫秒的英语单词是millisecond,简写为msec
#include <stdio.h>
#include <sys/time.h>
#include <time.h>
struct timeval tv;
while(1)
{
gettimeofday(&tv,NULL);
printf("time ∅n",tv.tv_sec,tv.tv_usec);
sleep(2);
}
return 0;
}
