CURLOPT_LOCALPORTRANGE(3)  curl_easy_setopt options  CURLOPT_LOCALPORTRANGE(3)

NAME
       CURLOPT_LOCALPORTRANGE - number of additional local ports to try

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOCALPORTRANGE,
                                 long range);

DESCRIPTION
       Pass  a long. The range argument is the number of attempts libcurl will
       make to find a working local port number. It starts with the given CUR‐
       LOPT_LOCALPORT(3) and adds one to the number for  each  retry.  Setting
       this option to 1 or below will make libcurl do only one try for the ex‐
       act  port number. Port numbers by nature are scarce resources that will
       be busy at times so setting this value to something too low might cause
       unnecessary connection setup failures.

DEFAULT
       1

PROTOCOLS
       All

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
         curl_easy_setopt(curl, CURLOPT_LOCALPORT, 49152L);
         /* and try 20 more ports following that */
         curl_easy_setopt(curl, CURLOPT_LOCALPORTRANGE, 20L);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Added in 7.15.2

RETURN VALUE
       Returns CURLE_OK if the option is supported,  and  CURLE_UNKNOWN_OPTION
       if not.
