KVSummaryInfoEx
This structure defines the parameters used by the VAPIM_GETSUMMARYINFO message. It provides a count of the number of metadata elements, and a pointer to the first element of the array of individual elements. (Metadata is also referred to as document summary information.)
Syntax
#include <kvtypes.h> typedef struct tag_KVSummaryInfoEx { int nElem; KVSumInfoElemEx *pElem; } KVSummaryInfoEx;
Members
The number of metadata elements contained in the array. This value is derived from the enumerated type |
|
Points to the first element of the array of document metadata elements defined by the KVSumInfoElemEx structure. |
Discussion
nElem
might be zero. This indicates that the document did not contain metadata, such as an ASCII text document. IfnElem
is not zero,nElem
is at least 42, and possibly more. This value is derived from theKVSumType
enumerated type inkvtypes.h
. The first 42 members ofpElem
are ordered according to the sort order ofKVSumType
. For example,pElem[0]
is the code page of the document, andpElem[10]
is the date the document was last printed.- If
nElem
is equal or greater than 42, the returned value is a non-standard metadata field.
