This function prepares to obtain credentials matching *creds* , either by retrieving them from *ccache* or by making requests to ticket-granting services beginning with a ticket-granting ticket for the client principal's realm.



The resulting TGS acquisition context can be used asynchronously with :c:func:`krb5_tkt_creds_step()` or synchronously with :c:func:`krb5_tkt_creds_get()` . See also :c:func:`krb5_get_credentials()` for synchronous use.



Use :c:func:`krb5_tkt_creds_free()` to free *ctx* when it is no longer needed.
