Coverity complains (CID 1460331, 1459482, 1459336, 1458895) that we call curl_easy_setopt(), which can return an error value, but we never check the return value.
Is it correct? Looking at the libcurl documentation, the function does return an error status, and there's nothing that says it's ok to ignore (e.g. that it's guaranteed that the library will safely accumulate any errors and return them when you make the subsequent curl_easy_perform() call). On the other hand, neither the libcurl manpage example nor the handful of example programs at https://curl.se/libcurl/c/example.html ever seem to check the return value from curl_easy_setopt()... thanks -- PMM
