ini文件解析c库(iniparser)【转】

转自：http://www.cnblogs.com/dyllove98/archive/2013/07/28/3221732.html

一.交叉编译ini解析库

.官方网站http://ndevilla.free.fr/iniparser

下载iniparser-3.1.tar.gz

.解压

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

make
.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

ini文件的格式(dictionary)

[section0]

key0 = value0

key1=value1

[section1]

key0 = value0

key1=value1
