CURLOPT_PROXYPORT - port number the proxy listens on
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYPORT, long port);
Pass a long with this option to set the proxy port to connect to unless it is
specified in the proxy string CURLOPT_PROXY(3) or uses 443 for https
proxies and 1080 for all others as default.
While this accepts a 'long', the port number is 16 bit so it
cannot be larger than 65535.
0, not specified which makes it use the default port
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
curl_easy_setopt(curl, CURLOPT_PROXY, "localhost");
curl_easy_setopt(curl, CURLOPT_PROXYPORT, 8080L);
