EVT_EVENT_METADATA_PROPERTY_ID enumeration (winevt.h)

  • Článek

Defines the identifiers that identify the metadata properties of an event definition.

Syntax

typedef enum _EVT_EVENT_METADATA_PROPERTY_ID {
  EventMetadataEventID,
  EventMetadataEventVersion,
  EventMetadataEventChannel,
  EventMetadataEventLevel,
  EventMetadataEventOpcode,
  EventMetadataEventTask,
  EventMetadataEventKeyword,
  EventMetadataEventMessageID,
  EventMetadataEventTemplate,
  EvtEventMetadataPropertyIdEND
} EVT_EVENT_METADATA_PROPERTY_ID;

Constants

 
EventMetadataEventID
Identifies the value attribute of the event definition. The variant type for this property is EvtVarTypeUInt32.
EventMetadataEventVersion
Identifies the version attribute of the event definition. The variant type for this property is EvtVarTypeUInt32.
EventMetadataEventChannel
Identifies the channel attribute of the event definition. The variant type for this property is EvtVarTypeUInt32. This property does not contain the channel identifier that you specified in the event definition but instead contains the value attribute of the channel. The value is zero if the event definition does not specify a channel.
EventMetadataEventLevel
Identifies the level attribute of the event definition. The variant type for this property is EvtVarTypeUInt32. This property does not contain the level name that you specified in the event definition but instead contains the value attribute of the level. The value is zero if the event definition does not specify a level.
EventMetadataEventOpcode
Identifies the opcode attribute of the event definition. The variant type for this property is EvtVarTypeUInt32. This property does not contain the opcode name that you specified in the event definition but instead contains the value attribute of the opcode. The value is zero if the event definition does not specify an opcode.
EventMetadataEventTask
Identifies the task attribute of the event definition. The variant type for this property is EvtVarTypeUInt32. This property does not contain the task name that you specified in the event definition but instead contains the value attribute of the task. The value is zero if the event definition does not specify a task.
EventMetadataEventKeyword
Identifies the keyword attribute of the event definition. The variant type for this property is EvtVarTypeUInt64. This property does not contain the list of keyword names that you specified in the event definition but instead contains a 64-bitmask of all the keywords. The top 16 bits of the mask are reserved for internal use and should be ignored when determining the keyword bits that the event definition set.
EventMetadataEventMessageID
Identifies the message attribute of the event definition. The variant type for this property is EvtVarTypeUInt32. The property contains the resource identifier that is assigned to the message string. To get the message string, call the EvtFormatMessage function. If the event definition does not specify a message, the value is –1.
EventMetadataEventTemplate
Identifies the template attribute of the event definition. The variant type for this property is EvtVarTypeString. This property does not contain the template name that you specified in the event definition but instead contains an XML string that includes the template node and each data node; the string does not include the UserData. The value is an empty string if the event definition does not specify a template.
EvtEventMetadataPropertyIdEND
This enumeration value marks the end of the enumeration values.

Remarks

The channel, level, opcode, task, and keyword properties return the value of the value attribute. To get the metadata for a property whose value is not zero, call the EvtGetPublisherMetadataProperty function for the property. For example, to get the metadata for the task property, call EvtGetPublisherMetadataProperty using the EvtPublisherMetadataTasks provider property identifier. The function returns an array of task objects that you enumerate. For each object, compare the value of the object's value property to the value specified in the event. If the values match, use the metadata from that object.
