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
       exact  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

RETURN VALUE

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