直接解释是：(void)0,把0强制转换为无类型,凡是用到assert_param(expr)的地方都用(void)0替换掉,具体功能看不出来
楼主把调用assert_param(expr)的地方贴出来看看

void (*restart)(void)=(void (*)(void))0x0;什么意思 javascipt:void(0)什么意思 ((void)0)是啥意思?#define assert_param(expr) ((void)0)本程序来自stm32f107/* @brief Enables or disables the High Speed APB (APB2) peripheral clock.*/void RCC_APB2PeriphClockCmd(uint32_t RCC_APB2Periph,FunctionalState NewState){/* Check the pa void interrupt (*)(void)什么意思 下面这段错误信息是啥意思,'TranslateAcceleratorA' :cannot convert parameter 2 from 'void *' to 'struct HACCEL__ *'Conversion from 'void*' to pointer to non-'void' requires an explicit cast 在让发光二极管第一个灯亮时“d1=0；”是啥意思 #include sbit d1=P0^0; void main() { d1=0; } void英文单词的意思 智商高的进来javascript:void(0)这是啥意思 THE APPROX QUANTITIES ARE:FOR VOID:1130 M FOR STAIRCASE:590 M 求出高手这句话是啥意思? 下列各个成员函数中,纯虚函数是（ ） A.void fun(int)=0 B.virtual void fun(int) C.virtual void fun 是C语言void create(dictionary **head)void create(dictionary **head){ if((*head=(dictionary*)malloc是表示什么意思呢 以下程序中,while 循环的次数是#include void main(void){ int i = 0;while (i void keyinterrupt() interrupt 2里 interrupt 是外部中断1的意思么? 下面一段C代码的意思typedef irqreturn_t (*irq_handler_t)(int,void*);static irqreturn_t pen_down_up_irq(int irq,void* dev_id){;}补充：pen_down_up_irq是irq_handler_t类型的 C51编译器,这个取值范围什么意思,假设sbit led1=P0∧0; void main （）C51编译器,这个取值范围什么意思,假设sbit led1=P0∧0;void main （）{led1=0;}是不是led1的取值范围是0和1? javascript:void(0)中的void的用法fanglor href=javascript:void(0) javascript:check_form();void(0);是什么意思
