Purpose of gnutls_credentials_set

[Florian Weimer]

I'm somewhat mystified what this function (and the surrounding
constructs) is supposed to do.  I'm calling
gnutls_certificate_set_x509_trust_mem and
gnutls_certificate_set_x509_key in the client, but in itself, that
does not cause failures when connecting to a server which presents the
wrong certificate, nor does it cause the client to send along a
certificate (for that, I've found that I have to install a callback
using gnutls_certificate_client_set_retrieve_function).  For
certificate verification to happen, it seems that I need to call
gnutls_certificate_verify_peers2 (or implement some sort of
verification manually).

Perhaps this could be clarified in the documentation?
