A pointer to BOOL is passed in the pvData parameter. Note that it's a pointer to BOOL, not an actual BOOL value, that is needed. As you found, changing to an IntByReference solved the problem, likely because an int and BOOL are the same size on your platform, and because now you'...
bool lengthCompare(const string &, const string &); 该函数的类型是bool (const string &, const string &)。要想声明一个可以指向该函数的指针,只需要指针替换函数名即可: bool (*pf) (const string &, const string &); //该指针还未初始化 这句语句的意思是,pf就是一个指向函数的指针,其中该函数...
uintptr // uintptr is an integer type that is large enough to hold the bit pattern of// any pointer.type uintptr uintptr uintptr是golang的内置类型,是能存储指针的整型,在64位平台上底层的数据类型是, typedefunsignedlonglongintuint64;typedefuint64 uintptr; 一个unsafe.Pointer指针也可以被转化为u...
一、QPointer 受保护的指针(A guarded pointer)QPointer<T>的行为类似于普通的 C++ 指针T*,但不同的是当所引用的对象被销毁时(普通的 C++ 指针则会变成“悬空指针”),QPointer会自动清除。T必须是QObject的子类。 当需要存储指向由其他人拥有的QObject的指针时,受保护的指针非常有用,因为在您仍然持有对它的...
