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. 42 43# DEFAULT 44 45CURLAUTH_BASIC 46 47# %PROTOCOLS% 48 49# EXAMPLE 50 51~~~c 52int main(void) 53{ 54 CURL *curl = curl_easy_init(); 55 if(curl) { 56 CURLcode ret; 57 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); 58 /* use this proxy */ 59 curl_easy_setopt(curl, CURLOPT_PROXY, "http://local.example.com:1080"); 60 /* allow whatever auth the proxy speaks */ 61 curl_easy_setopt(curl, CURLOPT_PROXYAUTH, CURLAUTH_ANY); 62 /* set the proxy credentials */ 63 curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "james:007"); 64 ret = curl_easy_perform(curl); 65 curl_easy_cleanup(curl); 66 } 67} 68~~~ 69 70# %AVAILABILITY% 71 72# RETURN VALUE 73 74curl_easy_setopt(3) returns a CURLcode indicating success or error. 75 76CURLE_OK (0) means everything was OK, non-zero means an error occurred, see 77libcurl-errors(3). 78
