read GpgmeData

[Florian Lindner]

Hello, 
I'm rather a C++ programmer than C, therefor I've little excperience with 
malloc, free and char[].
How can I get the result of gpgme_data_release_and_get_mem into a std::string 
object?

	GpgmeData data, output;
	gpgme_data_new(&data);
	gpgme_data_new_from_mem(&data, m_text.c_str(), m_text.size(), 1);
	gpgme_op_encrypt(m_ctx, rec, data, output);

	int length;
	gpgme_data_release_and_get_mem(output, &length);  // get the return value

Thx,
Florian
