使用c语言实现的跨平台INI文件解析库，下载地址：https://github.com/ndevilla/iniparser
解析库很小巧，1500行代码，4个文件，跨平台，没有依赖项目，使用 -ansi -pedantic C89 编译
使用起来很方便，官方例子如下：

#include <stdio.h>#include <stdlib.h>#include <string.h>#include <unistd.h>#include "iniparser.h"void create_example_ini_file(void);int  parse_ini_file(char * ini_name);int main(int argc, char * argv[]){    int     status ;    if (argc<2) {            /*创建示例ini文件，并解析*/           create_example_ini_file();        status = parse_ini_file("example.ini");    } else {        status = parse_ini_file(argv[1]);    }    return status ;}void create_example_ini_file(void){    FILE    *   ini ;    if ((ini=fopen("example.ini", "w"))==NULL) {        fprintf(stderr, "iniparser: cannot create example.ini\n");        return ;    }    fprintf(ini,    "#\n"    "# This is an example of ini file\n"    "#\n"    "\n"    "[Pizza]\n"    "\n"    "Ham       = yes ;\n"    "Mushrooms = TRUE ;\n"    "Capres    = 0 ;\n"    "Cheese    = Non ;\n"    "\n"    "\n"    "[Wine]\n"    "\n"    "Grape     = Cabernet Sauvignon ;\n"    "Year      = 1989 ;\n"    "Country   = Spain ;\n"    "Alcohol   = 12.5  ;\n"    "\n");    fclose(ini);}int parse_ini_file(char * ini_name){    dictionary  *   ini ;    /* Some temporary variables to hold query results */    int             b ;    int             i ;    double          d ;    const char  *   s ;    /*创建解析库句柄，所有数据存储在ini里面，所有操作也需要这个句柄*/    ini = iniparser_load(ini_name);    if (ini==NULL) {        fprintf(stderr, "cannot parse file: %s\n", ini_name);        return -1 ;    }    iniparser_dump(ini, stderr);    /* Get pizza attributes */    printf("Pizza:\n");    /*pizza是所属段明ham是段内参数名，iniparser_getboolean会将返回值转化成bool值*/    b = iniparser_getboolean(ini, "pizza:ham", -1);    printf("Ham:       [%d]\n", b);    b = iniparser_getboolean(ini, "pizza:mushrooms", -1);    printf("Mushrooms: [%d]\n", b);    b = iniparser_getboolean(ini, "pizza:capres", -1);    printf("Capres:    [%d]\n", b);    b = iniparser_getboolean(ini, "pizza:cheese", -1);    printf("Cheese:    [%d]\n", b);    /* Get wine attributes */    printf("Wine:\n");    /*获取string类型的值*/    s = iniparser_getstring(ini, "wine:grape", NULL);    printf("Grape:     [%s]\n", s ? s : "UNDEF");    /*获取int类型的值*/    i = iniparser_getint(ini, "wine:year", -1);    printf("Year:      [%d]\n", i);    s = iniparser_getstring(ini, "wine:country", NULL);    printf("Country:   [%s]\n", s ? s : "UNDEF");    /*获取double类型的值*/    d = iniparser_getdouble(ini, "wine:alcohol", -1.0);    printf("Alcohol:   [%g]\n", d);    /*用完之后不要忘记释放句柄，不然会有内存泄露*/    iniparser_freedict(ini);    return 0 ;}
