Linux 调试打印时间和颜色

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

void print_time(void)
{
    time_t curr_time;
    time(&curr_time);
    struct tm *ptm = localtime(&curr_time); 
    struct timeval tv;
    gettimeofday(&tv, NULL);

    printf("\033[31m[%04d-%02d-%02d %02d:%02d:%02d.%03d]\n", 
      ptm->tm_year + 1900, ptm->tm_mon + 1, ptm->tm_mday, ptm->tm_hour, ptm->tm_min, ptm->tm_sec, tv.tv_usec/1000);
}

红色 -> 31m
黄色 -> 33m
绿色 -> 32m
恢复白色 -> 0m
