The callback function is given the +connection in parameter B, a B-terminated PSK identity hint +sent by the server in parameter B, a buffer B of +length B bytes where the the resulting +B-terminated identity is to be stored, and a buffer B of +length B bytes where the resulting pre-shared key is to +be stored. + +=head1 NOTES + +Note that parameter B given to the callback may be B. + +=head1 RETURN VALUES + +Return values from the client callback are interpreted as follows: + +On success (callback found a PSK identity and a pre-shared key to use) +the length (> 0) of B in bytes is returned. + +Otherwise or on errors callback should return 0. In this case +the connection setup fails. + +=cut -- cgit v1.2.3
