PCAUTOMATION_TABLE structure (portcls.h)
The PCAUTOMATION_TABLE structure contains a miniport driver's master table of properties, methods, and events.
Syntax
typedef struct {
ULONG PropertyItemSize;
ULONG PropertyCount;
const PCPROPERTY_ITEM *Properties;
ULONG MethodItemSize;
ULONG MethodCount;
const PCMETHOD_ITEM *Methods;
ULONG EventItemSize;
ULONG EventCount;
const PCEVENT_ITEM *Events;
ULONG Reserved;
} PCAUTOMATION_TABLE, *PPCAUTOMATION_TABLE;
Members
PropertyItemSize
Specifies the size in bytes of the property structure used. Set this member to sizeof(PCPROPERTY_ITEM) or greater. See the following Remarks section.
PropertyCount
Specifies the number of property items in the Properties array.
Properties
Pointer to the filter's array of properties. This is an array of PCPROPERTY_ITEM structures.
MethodItemSize
Specifies the size in bytes of the methods structure used. Set this member to sizeof(PCMETHOD_ITEM) or greater. See the following Remarks section.
MethodCount
Specifies the number of method items in the Methods array.
Methods
Pointer to the filter's array of methods. This is an array of PCMETHOD_ITEM structures.
EventItemSize
Specifies the size in bytes of the event structure used. Set this member to sizeof(PCEVENT_ITEM) or greater. See the following Remarks section.
EventCount
Specifies the number of event items in the Events array.
Events
Pointer to the filter's array of events. This is an array of PCEVENT_ITEM structures.
Reserved
Reserved. Initialize to zero.
Remarks
Any of the structure's item pointers can be NULL, in which case the corresponding counts should be zero. For item tables that are not zero length, the item size should not be smaller than the size of the corresponding item structure that is defined in the header file portcls.h. The minimum size for a property, event, or method item is sizeof(PCPROPERTY_ITEM), sizeof(PCEVENT_ITEM), or sizeof(PCMETHOD_ITEM), respectively. The item size can be larger than this, in which case the item structure is followed by whatever private data the miniport driver appends to it. Item sizes should be a multiple of eight.
The IMiniport::GetDescription method outputs a PCFILTER_DESCRIPTOR structure that points to a PCAUTOMATION_TABLE structure that specifies the miniport driver's automation table.
