程序调试过程中的日志文件源码
主要运行在VC6++环境下！
1 日志文件记录源代码：
1 #include<stdio.h> 2 #include<assert.h> 3 #include<time.h> 4 void my_log(char *strlog) 5 { 6 7 int ret; 8 9 time_t t; 10 struct tm *tp; 11 char curTime[100] = {0}; 12 13 char filename[]="info.log"; 14 char *fopentype = "a+"; 15 FILE *fp = NULL; 16 fp = fopen(filename, fopentype); 17 if ( NULL == fp ) 18 { 19 20 printf("不能进行[%s]日志记录!\n", filename); 21 return; 22 23 } 24 25 assert(strlog!= NULL); 26 27 // 获取当前系统时间 28 t = time(NULL); 29 tp = localtime(&t); 30 sprintf(curTime, "%2.2d-%2.2d-%2.2d %2.2d:%2.2d:%2.2d", tp->tm_year+1900, tp->tm_mon+1, tp->tm_mday, tp->tm_hour, tp->tm_min, tp->tm_sec); 31 32 //存储日志 33 ret = fprintf(fp, "[%s] %s\n", curTime, strlog);//另起一行 34 if(ret >= 0) 35 { 36 fflush(fp); 37 } 38 39 fclose(fp); 40 return; 41 }
2 测试主函数
1 int main() 2 { 3 4 my_log("Save the log information for the first time "); 5 my_log("The second commit log information"); 6 my_log("The third log information"); 7 return 0; 8 }
3 最后文件中的信息
