Yes, you are right. The curl command works but if I write a test program using libcurl, libcurl does not automatically look for the variable. See https://curl.haxx.se/libcurl/c/CURLOPT_PROXY.html

    My test says differently:

    $ http_proxy=foooo:9999 curl localhost -v
    * Rebuilt URL to: localhost/
    * Uses proxy env variable http_proxy == 'foooo:9999'
    * Could not resolve proxy: foooo
    * Closing connection 0
