移植ini解析源码

要使用ini, 需要先#include "ini.h"，我们查看ini.h的头文件介绍如下：可以看到源码的github地址https://github.com/benhoyt/inih

用git clone https://github.com/benhoyt/inih.git ,下载源码。

编写代码test.c：

#include <stdio.h>
#include "ini.h"
#include <string.h>

typedef struct _SAMPLE_INI_CFG_S {
        char name[100];
        int bus_id;
        int age;
        char name2[100];
        int bus_id2;
        int age2;
} SAMPLE_INI_CFG_S;
static int parse_handler(void *user, const char *section, const char *name, const char *value)
{
        SAMPLE_INI_CFG_S *cfg = (SAMPLE_INI_CFG_S *)user;
        if (strcmp(section, "person1") == 0) {
                if (strcmp(name, "name") == 0) {
                        strcpy(cfg->name, value);
                } else if (strcmp(name, "bus_id") == 0) {
