GPGME and callbacks

[Craig Graham]

I have another gpgme problem.

The language I'm using (Labview) doesn't seem to do callbacks.This gives me
a problem in generating a signature since I cannot provide a callback
function in order to obtain the pass phrase. I need a mechanism by which I
can send the pass phrase through myself, either by pre-loading it into the
library as is done with the signing keys, or by passing it as one of the
arguments to a sign function.

Does a mechanism already exist for this, or do I have to change the library
myself?
