Filterドライバ送信OID Request現在のMACアドレスを取得
7320 ワード
1.目的:現在のNICのMACアドレスを取得する
2.方法:OIDの使用:OID_DOT11_CURRENT_ADDRESS
3.情報準備:
4.はfilterDoInterNalRequest関数(LWFドライバソースから)を実行する
これで完成~
Mac Address is 0-14-78-7a-88-b6
2.方法:OIDの使用:OID_DOT11_CURRENT_ADDRESS
3.情報準備:

Routine Description:
Utility routine that forms and sends an NDIS_OID_REQUEST to the
miniport, waits for it to complete, and returns status
to the caller.
NOTE: this assumes that the calling routine ensures validity
of the filter handle until this returns.
Arguments:
FilterModuleContext - pointer to our filter module context
RequestType - NdisRequest[Set|Query|method]Information
Oid - the object being set/queried
InformationBuffer - data for the request
InformationBufferLength - length of the above
OutputBufferLength - valid only for method request
MethodId - valid only for method request
pBytesProcessed - place to return bytes read/written
Return Value:
Status of the set/query request
