[jira] [Created] (ARROW-2317) [Python] fix C linkage warning

Viktor Gal created ARROW-2317:
---------------------------------

             Summary: [Python] fix C linkage warning
                 Key: ARROW-2317
                 URL: https://issues.apache.org/jira/browse/ARROW-2317
             Project: Apache Arrow
          Issue Type: Bug
            Reporter: Viktor Gal


When using pyarrow interface from a c++ library one will get the following compiler warning:
{quote}{{warning: 'unwrap_table' has C-linkage specified, but returns user-defined type 'arrow::Status' which is incompatible with C [-Wreturn-type-c-linkage]}}
{{ARROW_EXPORT Status unwrap_table(PyObject* table, std::shared_ptr<Table>* out);}}
{quote}
This is due to a Cython artifact.
