name : curl_errstr_raw.rst errstr_raw() -> byte string Return the internal libcurl error buffer of this handle as a byte string. Return value is a ``str`` instance on Python 2 and ``bytes`` instance on Python 3. Unlike :ref:`errstr_raw <errstr_raw>`, ``errstr_raw`` allows reading libcurl error buffer in Python 3 when its contents is not valid in Python's default encoding. On Python 2, ``errstr`` and ``errstr_raw`` behave identically. *Added in version 7.43.0.2.*
