'void*' is not a pointer-to-object type 错误的含义 'void*' is not a pointer-to-object type 这个错误通常出现在使用某些需要指针指向具体对象类型的C++模板或函数中时,错误地使用了 void* 类型指针。在C++中,void* 是一个通用指针类型,它可以指向任意类型的数据,但由于它本身不指向任何具体的对象类型,因...
cout<<*ptr; //Error Message: 'void*' is not a pointer-to-object type getch(); } Please help, why this error occuring? Dec 14, 2012 at 1:44pm Zhuge(4664) You tell the compiler to dereference ptr, but since ptr is void* it has no idea what the memory at ptr is meant to look...

Compiler Error: 'void*' is not a pointer-to-object type 下面这个代码是使用void指针存储整型类型的数据,并且void指针被强转为整型指针,并且被解引用。 // C program to dereference the void// pointer to access the value#include<stdio.h>intmain(){inta=10;void*ptr=&a;// The void pointer 'ptr...
'void *' is not a pointer-to-object type 或者有更好的方法来传递有关调用者对象的信息以及我可以传递给 void *user_data 的其他一些参数吗? 更新: @aaa carp建议的屁股我改变了 >> 到 > > ,前两个错误得到了解决。最后一点很奇怪,为什么我在这里投射时会得到那种消息而不是在设置回调时放置那个对象?
A pointer to member is NOT a pointer.itianda < 11 成员函数指针不是简单的地址 幻の上帝 小吧主 15 我记得C++11 void*到函数指针转换是conditionally supported,得查实现文档了。幻の上帝 小吧主 15 至于成员函数指针,肯定是不能指望直接转void*的。x86上对象指针和成员函数指针的sizeof基本上也都...
A consequence of this is that sizeof is also allowed on void and on function types, and returns 1. The option -Wpointer-arith requests a warning if these extensions are used. 意思是,在 GNU C中,指向 void 指针和指向函数的指针支持加法和减法操作。这是通过将 void 或函数的大小视为1来实现的...
