20CURLOPT_PROXYAUTH - HTTP proxy authentication methods
21
22# SYNOPSIS
23
24~~~c
25#include <curl/curl.h>
26
27CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYAUTH, long bitmask);
28~~~

30# DESCRIPTION
31
32Pass a long as parameter, which is set to a bitmask, to tell libcurl which
33HTTP authentication method(s) you want it to use for your proxy
34authentication. If more than one bit is set, libcurl first queries the site to
35see what authentication methods it supports and then it picks the best one you
36allow it to use. For some methods, this induces an extra network round-trip.
37Set the actual name and password with the CURLOPT_PROXYUSERPWD(3)
38option.
39
40The bitmask can be constructed by the bits listed and described in the
41CURLOPT_HTTPAUTH(3) man page.
