OID_TAPI_ACCEPT

  • Articolo

The OID_TAPI_ACCEPT OID requests the miniport driver to accept the specified call. Optionally, it requests that the miniport driver send the specified user-to-user information to the calling party.

Support for this request is optional.

The request uses an NDIS_TAPI_ACCEPT structure, defined as follows:

typedef struct _NDIS_TAPI_ACCEPT {         
         IN ULONG ulRequestID;
         IN HDRV_CALL hdCall;
         IN ULONG ulUserUserInfoSize;
         IN UCHAR UserUserInfo[1];
 } NDIS_TAPI_ACCEPT, *PNDIS_TAPI_ACCEPT;

The members of this structure contain the following information:

  • ulRequestID
    Reserved.

  • hdCall
    Specifies the miniport driver's handle to the call to be accepted. The driver set this handle up when it called NdisMIndicateStatus with the LINE_EVENT_NEWCALL indication.

  • ulUserUserInfoSize
    Specifies the size in bytes of the user-to-user information in UserUserInfo. If this member is zero, the miniport driver should ignore the next member.

  • UserUserInfo
    Specifies a string containing user-to-user information to be sent to the remote party as part of the call-accept operation. User-to-user information is sent only if supported by the underlying network (see OID_TAPI_GET_DEV_CAPS).

The MiniportSetInformationfunction can return one of the following:

NDIS_STATUS_SUCCESS

NDIS_STATUS_PENDING

NDIS_STATUS_TAPI_INVALCALLHANDLE

NDIS_STATUS_TAPI_INVALCALLSTATE

NDIS_STATUS_TAPI_RESOURCEUNAVAIL

NDIS_STATUS_TAPI_USERUSERINFOTOOBIG

NDIS_STATUS_FAILURE
