Subject: Agent API RequestInput method for requesting passphrases
X-Git-Tag: 2.0_alpha~2378
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b1527c31c9aa5ed571909dcde0a4c6851e829bd3;p=framework%2Fconnectivity%2Fconnman.git

Agent API RequestInput method for requesting passphrases

request_input_passphrase_reply creates and sends an Agent API RequestInput
method call and waits for the method call return. The function expects a
passhphrase_cb_t to be supplied. Only the "Passphrase" dictionary field is
requested by the method call and only the "Passphrase" dictionary field in
the method call return is used.
