CURLOPT_PROXY_SERVICE_NAME(3) Library Functions Manual
NAME
CURLOPT_PROXY_SERVICE_NAME - proxy authentication service name
SYNOPSIS
#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
