对“arithmetic on pointer to void or function type”的解答 指针及其基本用法: 指针是编程语言中的一种数据类型,它存储了另一个变量的内存地址。通过指针,我们可以直接访问和操作内存中的数据。在C和C++等语言中,指针被广泛使用以实现动态内存分配、数组操作、函数参数传递等功能。 c int a = 10; int *p ...
6.5.6-2: For addition, either both operands shall have arithmetic type, or one operand shall be a pointer to an object type and the other shall have integer type. So, the question here is whether void* is a pointer to an "object type", or equivalently, whether void is an "object ty...
So, the question here is whether void* is a pointer to an "object type", or equivalently, whether void is an "object type". The definition for "object type" is: 6.2.5.1: Types are partitioned into object types (types that fully describe objects) , function types (types that describe ...
警告解决方案: 在void*指针变量前加一个(uint8_t *),例如: //command.payload是指向void的指针类型 //修改之前: void* ptr = command.payload + command.len; //修改之后: void* ptr = (uint8_t *)command.payload + command.len;版权声明:本文为MashiMaroJ原创文章,遵循 CC 4.0 BY-SA 版权协议,转载...
warning: pointer of type 'void *' used in arithmetic 对void* 类型的指针进行加减运算的时候,这是不安全的,因为编译器并不知道你指针的单元是多少,需要移动多长的距离。作为扩展,大部分编译器都允许给void 指针做算术运算。
Anybody have any ideas how I could get this to work?struct mem_control_block {int is_available; int size; };void free(void *firstbyte) { struct mem_control_block *mcb; /* Backup from the given pointer to find the * mem_control_block...
than it really has, for example by casting the _function pointer_ to another type. For example, I've seen programs that did this: static int foo_qcmp(struct foo *a, struct foo *b); ... qsort(..., (int (*)(const void*, const void*)) foo_qcmp); ...
