CURLOPT_PROXYUSERPWD (3) Linux Manual Page
CURLOPT_PROXYUSERPWD – user name and password to use for proxy authentication
Synopsis
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYUSERPWD, char *userpwd);
Description
Pass a char * as parameter, which should be [user name]:[password] to use for the connection to the HTTP proxy. Both the name and the password will be URL decoded before use, so to include for example a colon in the user name you should encode it as %3A. (This is different to how CURLOPT_USERPWD(3) is used – beware.) Use CURLOPT_PROXYAUTH(3) to specify the authentication method.
