最近遇到这样一段有bug的代码:

#include<stdio.h>
#include<unistd.h>
#include <stdint.h>
#include <sys/time.h>

//微秒
uint64_t get_usec()
{
	struct timeval now;
	gettimeofday(&now, NULL);

	return now.tv_sec * 1000000 + now.tv_usec; 
}


int main()
{ 
	printf("%llu usec\n", get_usec());

	return 0;
} 

      秒破上述bug.
