我有一部法典:

#include <stdio.h>

typedef void (*FUNC_TYPE)(int value, int count, int* pt);

void func(int* ptr, int val, int cnt, int* pd)
{
    printf("ptr: %p, %d 
", ptr, *ptr);
    printf("cnt: %p, %d 
", &cnt, cnt);
    printf("val: %p, %d 
", &val, val);
    printf("pd: %p, %d 
", pd, *pd);
}
int main()
{
    int val = 10;
    int tmp = 20;
    int* pd = &tmp;
    ((FUNC_TYPE)(func))(val, tmp, pd);
    return 0;
}

亚洲开发银行职能之间经过争论的结果是:

func (ptr=0xa, val=20, cnt=-73208, pd=0x14) at test.c:7

谁能告诉我为什么发生这种情况?

我想知道如何通过不同类型的C语文职能之间的参数?

问题回答

职能<代码>func与职能点类别FUNC_TYPE不一致,因为论点数目并不相同。

将职能点定位为一种不相容的职能点,随后试图通过转换点触发器在你的代码中不明确的行为

因此,你没有做这种转换。
