Manpages - CURLOPT_PROXYPORT.3

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

All

  CURL *curl = curl_easy_init();

    curl_easy_setopt(curl, CURLOPT_PROXYPORT, 8080L);
