Sets the values of an event data descriptor.
void EventDataDescCreate( [out] PEVENT_DATA_DESCRIPTOR EventDataDescriptor, [in] const PVOID DataPtr, [in] ULONG DataSize );
- EventDataDescriptor [out]
The data descriptor whose member values are set to those of the remaining parameters. For details, see EVENT_DATA_DESCRIPTOR.
- DataPtr [in]
A pointer to the event data used to set the Ptr member of EVENT_DATA_DESCRIPTOR.
If the event data's type is a NULL-terminated string, the DataPtr parameter must not be NULL.
If the event data's type is a string whose size is described by some other field in the event, the DataPtr parameter may be NULL.
- DataSize [in]
The size of the event data. The value is used to set the Size member of EVENT_DATA_DESCRIPTOR.
This macro does not return a value.
This is a convenience macro for setting the members of the EVENT_DATA_DESCRIPTOR structure.
