有一份配置文件,程序运行时需要从中获取自己需要的信息。
要求:
1. 程序可以获取自己想要的任何标头(public,main_agent等)下key(server_ip等)对应的值(192.168.1.1等)
2. 使用两层链表实现,第一层链表为标头链表,每个标头链表下存在自己的key链表
3. 方法声明:
// 加载配置文件,将配置文件信息存于list链表中
// 参数1.链表头2配置文件绝对路径
// 返回值 -1失败 0成功
int load_config ( xlist *list , char *filename ) ;
// 获取配置文件某字段内容
// 参数1链表头2标头3key
// 返回值 NULL失败,成功返回字符串内容
char * get_config_value ( xlist *list , char *tag , char *key ) ;
配置文件内容如下:
[public]
server_ip=192.168.1.1
server_port=33000
encode_type=aes
request_time=10
heart_time=10
server_version=1.0
log_path=/home/c_log
[main_agent]
version=1.0
log_level=7
src_port=33001
[mon_file]
version=1.0
log_level=7
src_port=33002
