    # Error Codes (defined by libssh2)
    # The library once used -1 as a generic error return value on numerous
    # places through the code, which subsequently was converted to
    # LIBSSH2_ERROR_SOCKET_NONE uses over time. As this is a generic error code,
    # the goal is to never ever return this code but instead make sure that a
    # more accurate and descriptive error code is used.
