Questions about GPGME

What I would like is are functions like
gpgme_set_pubkeyring(char *file);
gpgme_set_seckeyring(char *file);
gpgme_set_no_default_keyring(int );
or something like that simple setting the gpg options accordingly.

I think that will work for me.

This sound good, I just can't get the verify (or decrypt_verify) working. I'm
using the folling code:

void Crypto::Test(char *msg) {
  size_t nread; 
  int	 ret,cnt=0;
  char  *buf_ptr;
  char str_out[MAX_DATA];
  GpgmeSigStat stat;
  GpgmeData in, out, out2;
  err = gpgme_data_new_from_mem(&in,msg,strlen(msg),0);
  if (err) throw CoreError(gpgme_strerror(err));
  err = gpgme_data_new ( &out );
  if (err) throw CoreError(gpgme_strerror(err));
  err = gpgme_op_sign (ctx,in,out,GPGME_SIG_MODE_NORMAL);
  if (err) throw CoreError(gpgme_strerror(err));
  fflush (NULL);
  err = gpgme_data_rewind ( out );
  if (err) throw CoreError(gpgme_strerror(err));
  err = gpgme_data_read(out,str_out, MAX_DATA, &nread );
  if(err) throw CoreError(gpgme_strerror(err));
  gpgme_data_release (in);
  gpgme_data_release (out);
  cout<<str_out<<endl;
  err = gpgme_data_new_from_mem(&in,str_out,strlen(str_out),1);
  bzero(str_out,sizeof(str_out));
  if (err) throw CoreError(gpgme_strerror(err));
  err = gpgme_data_new(&out2);
  if (err) throw CoreError(gpgme_strerror(err));
  err = gpgme_op_verify(ctx,in,out2,&stat);
  if (err) throw CoreError(gpgme_strerror(err));
  gpgme_data_release (in);
  gpgme_data_release (out);
  err = gpgme_data_rewind ( out2 );
  if (err) throw CoreError(gpgme_strerror(err));
  err = gpgme_data_read(out2,str_out, MAX_DATA, &nread );
  if(err) throw CoreError(gpgme_strerror(err));
  cout<<str_out;
}

When running it, I always get an No-Data-error from _op_verify(). But when
I give the signed output to gpg in the command line it's verifies correctly.
What am I doing wrong?

Thanks
