# NAME

CURLOPT_PROXY_SERVICE_NAME - proxy authentication service name

# SYNOPSIS

~~~c
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SERVICE_NAME,
                          char *name);
~~~

# DESCRIPTION

Pass a char pointer as parameter to a string holding the *name* of the
service. The default service name is **"HTTP"** for HTTP based proxies and
**"rcmd"** for SOCKS5. This option allows you to change it.

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

See above

    curl_easy_setopt(curl, CURLOPT_PROXY_SERVICE_NAME, "custom");
    ret = curl_easy_perform(curl);
  }
}
