NDIS_OPER_STATE structure (ntddndis.h)
The NDIS_OPER_STATE structure provides the current operational state of an NDIS network interface.
Syntax
typedef struct _NDIS_OPER_STATE {
NDIS_OBJECT_HEADER Header;
NET_IF_OPER_STATUS OperationalStatus;
ULONG OperationalStatusFlags;
} NDIS_OPER_STATE, *PNDIS_OPER_STATE;
Members
Header
The NDIS_OBJECT_HEADER structure for the NDIS_OPER_STATE structure. Set the Type member of the structure that Header specifies to NDIS_OBJECT_TYPE_DEFAULT, the Revision member to NDIS_OPER_STATE_REVISION_1, and the Size member to NDIS_SIZEOF_OPER_STATE_REVISION_1.
OperationalStatus
The NET_IF_OPER_STATUS operational status type.
OperationalStatusFlags
This member provides the reason why the OperationalStatus member is set to NET_IF_OPER_STATUS_DOWN or NET_IF_OPER_STATUS_DORMANT. This member is a ULONG value that contains a bitwise OR of a combination of the following flags:
NET_IF_OPER_STATUS_DOWN_NOT_AUTHENTICATED
The operational status is set to NET_IF_OPER_STATUS_DOWN because the default port of the miniport adapter is not authenticated.
NET_IF_OPER_STATUS_DOWN_NOT_MEDIA_CONNECTED
The operational status is set to NET_IF_OPER_STATUS_DOWN because the miniport adapter is not in a media-connected state.
NET_IF_OPER_STATUS_DORMANT_PAUSED
The operational status is set to NET_IF_OPER_STATUS_DORMANT because the miniport adapter is in the paused or pausing state.
NET_IF_OPER_STATUS_DORMANT_LOW_POWER
The operational status is set to NET_IF_OPER_STATUS_DORMANT because the miniport adapter is in a low power state.
Remarks
For the NDIS_STATUS_OPER_STATUS status indication, NDIS supplies an NDIS_OPER_STATE structure in the StatusBuffer member of the NDIS_STATUS_INDICATION structure.
NDIS_STATUS_OPER_STATUS indicates the current operational state of an NDIS network interface to overlying drivers.
