Function olm_sys::olm_pickle_account

pub unsafe extern "C" fn olm_pickle_account(
    account: *mut OlmAccount, 
    key: *const c_void, 
    key_length: usize, 
    pickled: *mut c_void, 
    pickled_length: usize
) -> usize

Stores an account as a base64 string. Encrypts the account using the supplied key. Returns the length of the pickled account on success. Returns olm_error() on failure. If the pickle output buffer is smaller than olm_pickle_account_length() then olm_account_last_error() will be “OUTPUT_BUFFER_TOO_SMALL”
