CURLOPT_PROXYUSERPWD(3) Library Functions Manual CURLOPT_PROXYUSERPWD(3)
NAME
CURLOPT_PROXYUSERPWD - username and password to use for proxy authenti-
cation
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYUSERPWD, char *userpwd);
DESCRIPTION
Pass a char pointer as parameter, which should be [username]:[password]
to use for the connection to the HTTP proxy. Both the name and the pass-
word are URL decoded before used, so to include for example a colon in
the username you should encode it as %3A. (This is different to how CUR-
LOPT_USERPWD(3) is used - beware.)
Use CURLOPT_PROXYAUTH(3) to specify the authentication method.
The application does not have to keep the string around after setting
this option.
Using this option multiple times makes the last set string override the
previous ones. Set it to NULL to disable its use again.
DEFAULT
NULL
PROTOCOLS
This functionality affects all supported protocols
