Added in curl 7.19.4

See above

Deprecated since 7.49.0

Deprecated since 7.49.0. Use CURLOPT_PROXY_SERVICE_NAME(3) instead. Pass a char pointer as parameter to a string holding the name of the service. The default service name for a SOCKS5 server is rcmd. This option allows you to change it. The application does not have to keep the string around after setting this option.
