NCB里面的PUCHAR ncb_buffer改怎么赋值呀？

[certbuggy]

有没有一份比较详尽的VC数据类型使用说明？类型太多，我都被他们告糊涂了。

PUCHAR也就是无符号字符型指针。(unsigned char*)
ncb_buffer需要一个ASTAT结构体的对象的指针。强制转换并赋值就可以了。
顺便说一句，MSDN中对数据类型有详细的说明啊。

下边是一个完整的程序。可以参考一下^-^

}

// Get all of the local ethernet addresses
string sMAC;
for (int i = 0; i < AdapterList.length; ++i) {
if (GetAdapterInfo(AdapterList.lana[i], sMAC)) {
cout << "Adapter " << int (AdapterList.lana[i]) <<
"'s MAC is " << sMAC << endl;
}
else {
cerr << "Failed to get MAC address! Do you" << endl;
cerr << "have the NetBIOS protocol installed?" << endl;
break;
}
}
return 0;
}

以上.

就是一个字符型的指针
