Function olm_sys::olm_unpickle_inbound_group_session

pub unsafe extern "C" fn olm_unpickle_inbound_group_session(
    session: *mut OlmInboundGroupSession, 
    key: *const c_void, 
    key_length: usize, 
    pickled: *mut c_void, 
    pickled_length: usize
) -> usize

Loads a group session from a pickled base64 string. Decrypts the session using the supplied key.

Returns olm_error() on failure. If the key doesn't match the one used to encrypt the account then olm_inbound_group_session_last_error() will be "BAD_ACCOUNT_KEY". If the base64 couldn't be decoded then olm_inbound_group_session_last_error() will be "INVALID_BASE64". The input pickled buffer is destroyed
