宏定义搭配##，引用时遇到报错does not give a valid preprocessing token，请教下如何解决

typedef struct
{
    char eLogState;
    char *pcPassword;
} CFG_LOG_T;

typedef struct
{
    unsigned int    Enable;
    unsigned char    Func;
    unsigned int    LevelNum;
    const unsigned int *pLevelTab;
} CFG_ADC_T;

typedef struct {
    CFG_LOG_T         CFG_LOG_TO;
    CFG_ADC_T         CFG_ADC_TO[4];
} CFG_SDK_T;
CFG_SDK_T const *GetSDKConfig(void);
#define GET_SDK_CFG(type_) ((type_ *)(&(GetSDKConfig()->type_##O)))

static CFG_SDK_T gstSDKConfig =
{
   
    .CFG_LOG_TO =
    {
        .eLogState = 1,        
        .pcPassword = "123456",
    },
   
    .CFG_ADC_TO[0] =
    {
        .Enable = 1,
        .Func = 1,
        .LevelNum = 3,
        .pLevelTab = ADC_DataLevelTab,
    },
    .CFG_ADC_TO[1] =
    {
        .Enable = 1,
        .Func = 1,
        .LevelNum = 3,
        .pLevelTab = ADC_DataLevelTab,
    },
    .CFG_ADC_TO[2] =
    {
        .Enable = 1,
        .Func = 1,
        .LevelNum = 3,
        .pLevelTab = ADC_DataLevelTab,
    },
    .CFG_ADC_TO[3] =
    {
        .Enable = 0,
        .Func = 1,
        .LevelNum = 3,
        .pLevelTab = ADC_DataLevelTab,
    },
};

int main (int argc, char *argv[])
{
    //这样调用没问题
    if (GET_SDK_CFG(CFG_LOG_T)->eLogState == 1)
    {
   
    }

 
    这样调用会报错 pasting "]" and "O" does not give a valid preprocessing token
    if(GET_SDK_CFG(CFG_ADC_T[0])->Func == 1)
    {
        
    }

 
    return 0;
}
