No way.  data.h is internal to gpgme and not part of the API.  It may
change with any release.  Internal data structures may never be used by
other applications or even language bindings.  The reason why
gpgme_data_t is an opaque pointer is just to not expose it in the API.

A language binding need to take this as an opaque pointer and is not
allowed to assume anything about it.  The only exception is NULL, which
means that the data object is not allocated.


Salam-Shalom,
