ini文件解析c库(iniparser) 移植

一.交叉编译ini解析库

1.官方网站http://ndevilla.free.fr/iniparser
建议下载：

下载iniparser-3.1.tar.gz

2.解压

tar -zxvf iniparser-3.1.tar.gz 
cd tar -zxvf iniparser

3.修改makefile

CC	= gcc  修改为--> CC	= arm-none-linux-gnueabi-gcc
AR	= ar   修改为--> AR	= arm-none-linux-gnueabi-ar

4.编译

make

5.拷贝src下的头文件dictionary.h和iniparser.h以及压缩包目录下的静态库libiniparser.a和动态库libiniparser.so.0到目标文件系统的对应目录下

二.iniparser库API

int iniparser_getnsec(dictionary * d);	//获取dictionary对象的section个数
char * iniparser_getsecname(dictionary * d, int n);	//获取dictionary对象的第n个section的名字
void iniparser_dump_ini(dictionary * d, FILE * f);	//保存dictionary对象到file
void iniparser_dumpsection_ini(dictionary * d, char * s, FILE * f);	//保存dictionary对象一个section到file
void iniparser_dump(dictionary * d, FILE * f);	//保存dictionary对象到file
int iniparser_getsecnkeys(dictionary * d, char * s);	//获取dictionary对象某个section下的key个数
char ** iniparser_getseckeys(dictionary * d, char * s);	//获取dictionary对象某个section下所有的key
char * iniparser_getstring(dictionary * d, const char * key, char * def);	//返回dictionary对象的section:key对应的字串值
int iniparser_getint(dictionary * d, const char * key, int notfound);	//返回idictionary对象的section:key对应的整形值
double iniparser_getdouble(dictionary * d, const char * key, double notfound);	//返回dictionary对象的section:key对应的双浮点值
int iniparser_getboolean(dictionary * d, const char * key, int notfound);	//返回dictionary对象的section:key对应的布尔值
int iniparser_set(dictionary * ini, const char * entry, const char * val);	//设置dictionary对象的某个section:key的值
void iniparser_unset(dictionary * ini, const char * entry);	//删除dictionary对象中某个section:key
int iniparser_find_entry(dictionary * ini, const char * entry) ;	//判断dictionary对象中是否存在某个section:key
dictionary * iniparser_load(const char * ininame);	//解析dictionary对象并返回(分配内存)dictionary对象
void iniparser_freedict(dictionary * d);	//释放dictionary对象(内存)

unsigned dictionary_hash(const char * key);	//计算关键词的hash值
dictionary * dictionary_new(int size);	//创建dictionary对象
void dictionary_del(dictionary * vd);	//删除dictionary对象
char * dictionary_get(dictionary * d, const char * key, char * def);	//获取dictionary对象的key值
int dictionary_set(dictionary * vd, const char * key, const char * val);	//设置dictionary对象的key值
void dictionary_unset(dictionary * d, const char * key);	//删除dictionary对象的key值
void dictionary_dump(dictionary * d, FILE * out);	//保存dictionary对象

		

	编写ini文件：
			

#ini file for example

[tcp]
;for tcp communication port = 8000;
ip = 127.0.0.1;
family = AF_INET;

[serial port]
;for serial port communication

speed = 9600;

    {

    } printf("dictionary obj:\n");
    iniparser_dump(ini,stderr);//save ini to stderr printf("\n%s:\n",iniparser_getsecname(ini,0));//get section name
    n = iniparser_getint(ini,"tcp:port",-1); printf("port : %d\n",n);

    str = iniparser_getstring(ini,"tcp:ip","null"); printf("ip : %s\n",str);

    str = iniparser_getstring(ini,"tcp:family","null"); printf("family : %s\n",str); printf("\n%s:\n",iniparser_getsecname(ini,1));
    n = iniparser_getint(ini,"serial port:speed",-1); printf("speed : %d\n",n);

    iniparser_freedict(ini);//free dirctionary obj return 0;
}

	结果：
		
dictionary obj:
[tcp]=UNDEF
[tcp:port]=[8000]
[tcp:ip]=[127.0.0.1]
[tcp:family]=[AF_INET]
[serial port]=UNDEF
[serial port:speed]=[9600]

tcp: port : 8000 ip : 127.0.0.1 family : AF_INET

serial port:
speed : 9600
