C语言我自己的宏定义

20220420 在打印格式化内容前加上当前时间

（定义）

//arnold 20220420 ky_printf_format_time() start
		void ky_printf_format_time(){
				char format_time[64] = {0};
				int ret = ky_get_format_time(format_time, sizeof(format_time));
				if(ret == 0){
						printf("ky_printf_string_and_format_time get format time failed!\n");
				}
				printf("[%s]", format_time);
		}
//arnold 20220420 ky_printf_format_time() end

#define KY_PRINTF_STRING_AND_FORMAT_TIME ky_printf_format_time();printf

（调用）

KY_PRINTF_STRING_AND_FORMAT_TIME("The program is going to be ended!\n");

int sig = 15;
KY_PRINTF_STRING_AND_FORMAT_TIME("demo_signal_call_back has received signal [%d]\n", sig);

（结果）

[2022-04-20_14-08-50]The program is going to be ended!

[2022-04-20_14-08-50]demo_signal_call_back has received signal [15]
