Ini 文件的解析

ini文件解析:
iniparser-3.1
sudo tar xvf iniparser-3.1.tar.gz
sudo make ———-生成静态库libiniparser.a 和动态库libiniparser.so.0

头文件及源码放在 src 目录中
cd test 应用的例子参考iniexample.c parse.c

将iniexample.c copy到上级目录，目录结构如下:

AUTHORS html INSTALL libiniparser.so.0 Makefile src
doc iniexample.c libiniparser.a LICENSE README test

如何编译 iniexamp.c ??? 需要用到动态库及头文件
gcc -o app iniexample.c -I ./src -L. -liniparser （注意 L 后的 . 不可或缺）

ini = iniparser_load(ini_name); // 将ini 文件读取到结构体中
iniparser_dump(ini, stderr); // 将ini 文件内容输出到终端上
b = iniparser_getboolean(ini, "pizza:ham", -1); //返回bool型数据
s = iniparser_getstring(ini, "wine:grape", NULL); 得到字符串型数据
i = iniparser_getint(ini, "wine:year", -1); 得到整形
d = iniparser_getdouble(ini, "wine:alcohol", -1.0); 得到 double
iniparser_freedict(ini); 将结构体内容释放

使用:

int main(int argc, char * argv[])
{
    int     status ;

    if (argc<2) {
        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 ;

    ini = fopen("example.ini", "w");
    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 ;
    char        *   s ;

    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");

    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");
    s = iniparser_getstring(ini, "wine:grape", NULL);
    printf("Grape:     [%s]\n", s ? s : "UNDEF");

    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");

    d = iniparser_getdouble(ini, "wine:alcohol", -1.0);
    printf("Alcohol:   [%g]\n", d);

    iniparser_freedict(ini);
    return 0 ;
}
