困扰我的问题

[wgch007]

bytebuf=(unsigned char* )malloc(100);
if(bytebuf==NULL)
printf("分配内存失败\n");

dwordbuf=(unsigned long int *)bytebuf[2];

dwordbuf[0]=(unsigned long int)46136;//这里为什么编译不同呀
请求高手指教

dwordbuf 怎么声明的啊?
从这句看
dwordbuf=(unsigned long int *)bytebuf[2];
dwordbuf是unsigned long int型的

那怎么可以用dwordbuf[0]?当然错了。

如果dwordbuf是unsigned long int *,则应该是:
unsigned long int *dwordbuf;
dwordbuf = (unsigned long int *)(bytebuf+2);
*(dwordbuf) = (unsigned long int)46136;

thank you very much!!
