gpgme_data_new_from_mem works, gpgme_data_write doesn't

[Nico Schottelius]

Hello!

I am testing around with gpgme and it seems I am doing something
wrong with gpgme_data_write():

If I do

   gerr = gpgme_data_new(&g_test);
   if(gerr != GPG_ERR_NO_ERROR) return 20;
   i = strlen(b_encrypt);  

   /* THIS WORKS */
   gerr = gpgme_data_new_from_mem(&g_encrypt_send, b_encrypt, i, 1);
   if(gerr != GPG_ERR_NO_ERROR) return 24;

   /* decrypt: from gpgme_data_new_from_mem()  */
   gerr = gpgme_op_decrypt(g_context, g_encrypt_send, g_plain_recv);
   if(gerr != GPG_ERR_NO_ERROR) {
      printf("gerr=%d\n",gerr);
      return 19;
   }


it works. If I do

   gerr = gpgme_data_new(&g_test);
   if(gerr != GPG_ERR_NO_ERROR) return 20;
   i = strlen(b_encrypt);  
   printf("strlen(%s) = %d\n",b_encrypt,i);

   /* THIS DOES NOT WORK */
   tmp = gpgme_data_write(g_test, b_encrypt, i);
   printf("gpgmedatawrite: %d\n", tmp);

   /* decrypt: from gpgme_data_write() */
   gerr = gpgme_op_decrypt(g_context, g_test, g_plain_recv2);
   if(gerr != GPG_ERR_NO_ERROR) {
      printf("gerr=%d\n",gerr);
      return 41;
   }

it does *NOT* work.

I created a testfile, containing both cases to show it in
commit 86f3d41a53834231eea54da750bd4564c9c13ae0 of ceofhack.

Anyone a hint, what I am doing wrong in the latter case?

Sincerly

Nico
