How do I check if the 3ds charger is plugged in?
问题
I am writing a function to know whether or not the charger is plugged in my 3DS. However, my function keeps returning false while the charger is plugged in.
I expect my function to return true if the charger is plugged into my 3DS.
Here is the function:
bool isChargerPluggedin() {
bool chargeState;
PTMU_GetAdapterState(&chargeState);
return chargeState == 1;
}
My first attempt to solve my problem was to allocate memory to the chargeState variable:
bool isChargerPluggedin() {
bool *chargeState = new bool;
PTMU_GetAdapterState(chargeState);
bool state = *chargeState == 1;
delete chargeState;
return state;
}
My second attempt was by using a global variable for chargeState instead of a local variable:
bool chargeState;
bool isChargerPluggedin() {
PTMU_GetAdapterState(&chargeState);
return chargeState == 1;
}

为了解决这个问题，你必须在你的主函数中首先使用函数 ptmuInit 初始化库。在程序退出之前，你必须反初始化这个库。以下是一个示例：
int main() {
ptmuInit();
// 程序循环
while (true) {
bool isPlugged = isChargerPluggedin();
...
}
ptmuExit();
}
英文:
To fix this, you must initialize first the libraries in your main function using the function ptmuInit. You must deinitialize the library before your program exitHere is a example:
int main() {
ptmuInit();
// program loop
while (true) {
bool isPlugged = isChargerPluggedin();
...
}
ptmuExit();
}
