fz_meta: Perform a meta operation on a document.
(In development - Subject to change in future versions)
Meta operations provide a way to perform format specific
operations on a document. The meta operation scheme is
designed to be extensible so that new features can be
transparently added in later versions of the library.
doc: The document on which to perform the meta operation.
key: The meta operation to try. If a particular operation
is unsupported on a given document, the function will return
FZ_META_UNKNOWN_KEY.
ptr: An operation dependent (possibly NULL) pointer.
size: An operation dependent integer. Often this will
be the size of the block pointed to by ptr, but not always.
Returns an operation dependent value; FZ_META_UNKNOWN_KEY
always means "unknown operation for this document". In general
FZ_META_OK should be used to indicate successful operation.
