Function olm_sys::olm_pk_get_private_key

pub unsafe extern "C" fn olm_pk_get_private_key(
    decryption: *mut OlmPkDecryption, 
    private_key: *mut c_void, 
    private_key_length: usize
) -> usize

Get the private key for an OlmDecryption object as an unencoded byte array private_key must be a pointer to a buffer of at least olm_pk_private_key_length() bytes and this length must be passed in private_key_length. If the given buffer is too small, returns olm_error() and olm_pk_encryption_last_error() will be “OUTPUT_BUFFER_TOO_SMALL”. Returns the number of bytes written.
