传递unsigned long 参数的问题

[zyqin]

执行结果：
jieguo11111:122
jieguo22222:-12975872 为什么不是122

如何才能输出122呢？


void ggg(sss)
unsigned long sss;
{
sss = 122;
printf("jieguo11111:%d\n",sss);
}


void main(){
unsigned long bbb;

ggg(bbb);


printf("jieguo22222:%d\n",bbb);


}

[goodname]

void ggg(sss)
unsigned long *sss;
{
sss = 122;
printf("jieguo11111:%d\n",sss);
}


void main(){
unsigned long bbb;

ggg(&bbb);


printf("jieguo22222:%d\n",bbb);


}

jieguo22222:0

不是122。

[goodname]

void ggg(sss)
unsigned long *sss;
{
*sss = 122;这里写错了,sorry
printf("jieguo11111:%d\n",sss);
}


void main(){
unsigned long bbb;

ggg(&bbb);


printf("jieguo22222:%d\n",bbb);


}

再写一个，不能再图快了。

void ggg(unsigned long *sss)
{
*sss = 122;
printf("jieguo11111:%ld\n",*sss);
}


void main(){
unsigned long bbb;

ggg(&bbb);


printf("jieguo22222:%ld\n",bbb);

}

非常感谢！
