fpGetSubFileMetadataList()
Containers can store metadata about their subfiles that is independent of the metadata stored within those subfiles. This function allows you to retrieve the metadata stored within the container about a particular subfile.
Syntax
KVErrorCode pascal fpGetSubFileMetadataList( void* const pFile, KVGetSubFileMetadataListArg args, const KVMetadataList** const ppMetadataList);
Arguments
pfile
|
The identifier of the container file - a file handle that you obtained by calling fpOpenFile() |
args
|
A KVGetSubFileMetadataListArg structure, which specifies how to retrieve the subfile metadata. |
ppMetadataList
|
A pointer to a KVMetadataList*. On success, fpGetSubFileMetadataList() sets this pointer to the address of a new KVMetadataList that contains the function pointers for accessing metadata elements. |
Returns
The return value is an error code.
Lifetime and Memory Management
You must free the KVMetadataList pointer by using its fpFree() function. You must free this pointer before you call fpCloseFile().
Discussion
Before retrieving any subfile metadata, you must get the main file information by calling fpGetMainFileInfo().
