passthru很奇怪的报错 [复制链接]

在passthru种，部分代码如下：
int PacketSize;
PUCHAR pPacketContent;
PUCHAR pBuf;
UINT BufLength;

NdisQueryPacket(MyPacket,NULL,NULL,NULL,&PacketSize);
NdisAllocateMemory(&pPacketContent,2000,0,HighestAcceptableMax);
NdisZeroMemory(pPacketContent, 2000);
NdisQueryBufferSafe(MyPacket->Private.Head, &pBuf, &BufLength, 32);
NdisMoveMemory(pPacketContent, pBuf, BufLength);

报错为：
myioctl.cpp(37) : error C2440: 'initializing' : cannot convert from 'int *' to 'unsigned int *'
myioctl.cpp(38) : error C2664: 'NdisAllocateMemory' : cannot convert parameter 1 from 'unsigned char ** ' to 'void ** '
myioctl.cpp(40) : error C2664: 'NdisQueryBufferSafe' : cannot convert parameter 2 from 'unsigned char ** ' to 'void ** '
myioctl.cpp(51) : error C2664: 'NdisQueryBufferSafe' : cannot convert parameter 2 from 'unsigned char ** ' to 'void ** '

很奇怪啊，在另一个程序passthur里都可以正常通过的，x现在做代码迁移，为什么在这里就不行了呢？真是奇怪，请大侠指点
