求高手帮写个c++读写配置文件类的实现代码
已知
//IM_Config_Parser.h
class IM_Config_Parser
{
public:
IM_Config_Parser(const char* file_name);
virtual ~IM_Config_Parser(void);
public:
bool open();
//根据信息类型strType和键strKey获取键值strValue
bool get_string(const char* strType,const char* strKey,char* strValue,const int& nMaxLen);
//根据信息类型strType和键strKey更新键值strValue
bool update_string(const char* strType,const char* strKey,const char* strValue);
private:
string _file_name;
fstream _file;
};
求IM_Config_Parser的实现
附配置文件格式示例Config.ini
[im_appclient] //信息类型，两边用[]括起来
im_ip=127.0.0.1 //键和键值，中间用=连接
im_udp_port=5402
clien_udp_port=5001
recent_ID=10001
[im_appserver]
db_ip=127.0.0.1
db_port=3306
db_name=myid
db_user=myid
db_pwd=myid
im_ip=127.0.0.1
im_udp_port=5402
recv_producer_num=1
send_consumer_num=1
process_consumer_num=10
