NDIS_SWITCH_PROPERTY_CUSTOM structure (ntddndis.h)
The NDIS_SWITCH_PROPERTY_CUSTOM structure specifies a custom profile property for the Hyper-V extensible switch.
Independent software vendors (ISVs) define the format for the custom properties. The format of the custom property is proprietary to the ISV.
Syntax
typedef struct _NDIS_SWITCH_PROPERTY_CUSTOM {
NDIS_OBJECT_HEADER Header;
ULONG Flags;
ULONG PropertyBufferLength;
ULONG PropertyBufferOffset;
} NDIS_SWITCH_PROPERTY_CUSTOM, *PNDIS_SWITCH_PROPERTY_CUSTOM;
Members
Header
The type, revision, and size of the NDIS_SWITCH_PROPERTY_CUSTOM structure. This member is formatted as an NDIS_OBJECT_HEADER structure.
The Type member of Header must be set to NDIS_OBJECT_TYPE_DEFAULT. To specify the version of the NDIS_SWITCH_PROPERTY_CUSTOM structure, the Revision member of Header must be set to the following value:
NDIS_SWITCH_PROPERTY_CUSTOM_REVISION_1
Original version for NDIS 6.30 and later.
Set the Size member to NDIS_SIZEOF_NDIS_SWITCH_PROPERTY_CUSTOM_REVISION_1.
Flags
A ULONG value that contains a bitwise OR of flags. This member is reserved for NDIS.
PropertyBufferLength
A ULONG value that specifies the size, in bytes, of the buffer that contains the custom extensible switch property.
PropertyBufferOffset
A ULONG value that specifies the offset, in bytes, to the property buffer. The offset is measured from the start of the NDIS_SWITCH_PROPERTY_CUSTOM structure up to the beginning of the property buffer.
Remarks
The NDIS_SWITCH_PROPERTY_CUSTOM structure is used in the following OID set requests:
The NDIS_SWITCH_PROPERTY_CUSTOM structure follows the NDIS_SWITCH_PROPERTY_PARAMETERS structure in the buffer that is associated with these OID set requests. The InformationBuffer member of the NDIS_OID_REQUEST structure contains a pointer to this buffer.Extensible switch extensions can access the custom extensible switch property buffer that is specified by an NDIS_SWITCH_PROPERTY_CUSTOM structure by using the NDIS_SWITCH_PROPERTY_CUSTOM_GET_BUFFER macro.
