KVMetadataType
This enumerated type defines the data type of metadata that can be extracted from a subfile in a mail message or mail store. If a metadata field has a corresponding KeyView type in KVMetadataType
, the metadata is converted to the KVMetadataElem structure, and the structure member isDataValid
is 1
. This enumerated type is defined in kvtypes.h
.
