使用malloc和struct的分段错误（核心已转储）

Question

我不明白为什么这个简单的代码没有在linux上导致分段错误的情况下无法运行：#include <stdlib.h>struct entry{   int value;};void initEntry(struct entry *entry){  entry = malloc(sizeof(struct entry));      entry->value = 0;}int main(){  struct entry *list;  initEntry(list);      list->value = 5;}删除最后一条指令（list->value = 5;）后，我可以运行该程序我编译：gcc main.c -o main

Answer 1

代码运行，但是我在编译过程中main.c:31:13: warning: passing argument 1 of ‘initEntry’ from incompatible pointer type [-Wincompatible-pointer-types]    initEntry(&list);              ^ main.c:24:6: note: expected ‘struct entry *’ but argument is of type ‘struct entry **’  void initEntry(struct entry *entry) {
