NAME

       CURLINFO_PRIMARY_PORT - get the latest destination port number

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIMARY_PORT, long *portp);

DESCRIPTION

       Pass  a  pointer  to  a long to receive the destination port of the most recent connection
       done with this curl handle.

       This is the destination port of the actual TCP or UDP connection libcurl used.  If a proxy
       was  used  for the most recent transfer, this is the port number of the proxy, if no proxy
       was used it is the port number of the most recently accessed URL.

PROTOCOLS

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
           res = curl_easy_perform(curl);
           if(res == CURLE_OK) {
             long port;
             res = curl_easy_getinfo(curl, CURLINFO_PRIMARY_PORT, &port);
             if(!res)
               printf("Connected to remote port: %ld\n", port);
           }
