# NAME

CURLOPT_PROXYUSERPWD - username and password to use for proxy authentication

# SYNOPSIS

~~~c
#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 password 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 CURLOPT_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.

# DEFAULT

This is NULL by default.

# PROTOCOLS

Used with all protocols that can use a proxy

# EXAMPLE

~~~c
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
    curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:8080");
    curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "clark%20kent:superman");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
~~~

# AVAILABILITY

Always

# RETURN VALUE

Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
