NAME

       CURLOPT_PROXYAUTH - HTTP proxy authentication methods

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYAUTH, long bitmask);

DESCRIPTION

       Pass  a  long  as  parameter,  which  is  set  to  a  bitmask,  to tell libcurl which HTTP
       authentication method(s) you want it to use for your proxy authentication.  If  more  than
       one  bit  is  set,  libcurl  first  queries the site to see what authentication methods it
       supports and then it picks the best one you allow  it  to  use.  For  some  methods,  this
       induces  an  extra  network  round-trip.   Set  the  actual  name  and  password  with the
       CURLOPT_PROXYUSERPWD(3) option.

       The bitmask can be constructed by the bits listed and described in the CURLOPT_HTTPAUTH(3)
       man page.

DEFAULT

       CURLAUTH_BASIC

PROTOCOLS

       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode ret;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           /* use this proxy */
           curl_easy_setopt(curl, CURLOPT_PROXY, "http://local.example.com:1080");
           /* allow whatever auth the proxy speaks */
           curl_easy_setopt(curl, CURLOPT_PROXYAUTH, CURLAUTH_ANY);
           /* set the proxy credentials */
           curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "james:007");
           ret = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }

RETURN VALUE

       Returns   CURLE_OK   if   the   option  is  supported,  CURLE_UNKNOWN_OPTION  if  not,  or
