This is both pretty complicated thorugh GPGME, as there is indeed not a direct
interface. Kleopatra and GPA use the "AssuanEngine" of GPGME to connect to the
gpg-agent's assuan interface and issue / parse commands directly through that
You might want to take a look at GPA's implementation:
Alternatively instead of wrapping gpg (and using the complicated edit
interface) you could also wrap "gpg-connect-agent" and issue commands to
scdaemon through that.
