为了方便日志的书写，进行日志输出宏定义
#include <stdio.h>#include <memory.h>#include <time.h>// 调试日志信息#define LOG_INFO(format, ...)                                                              \{                                                                                          \    time_t t = time(0);                                                                    \    struct tm ptm;                                                                         \    memset(&ptm, 0, sizeof(ptm));                                                          \    localtime_r(&t, &ptm);                                                                 \    fprintf(stdout, "[ INFO ] [ %4d-%02d-%02d %02d:%02d:%02d ] [ %s:%s:%d ] " format "",   \            ptm.tm_year + 1900, ptm.tm_mon + 1, ptm.tm_mday, ptm.tm_hour,                  \            ptm.tm_min, ptm.tm_sec, __FILE__, __FUNCTION__ , __LINE__, ##__VA_ARGS__);     \}// 错误日志信息#define LOG_ERROR(format, ...)                                                             \{                                                                                          \    time_t t = time(0);                                                                    \    struct tm ptm;                                                                         \    memset(&ptm, 0, sizeof(ptm));                                                          \    localtime_r(&t, &ptm);                                                                 \    fprintf(stderr, "[ ERROR] [%4d-%02d-%02d %02d:%02d:%02d ] [ %s:%s:%d ] " format "",    \            ptm.tm_year + 1900, ptm.tm_mon + 1, ptm.tm_mday, ptm.tm_hour,                  \            ptm.tm_min, ptm.tm_sec, __FILE__, __FUNCTION__ , __LINE__, ##__VA_ARGS__);     \}int main(){LOG_INFO("debug something %d !\n", 1);LOG_ERROR("something error %d !\n", 1);return 0;}
