CURLOPT_SERVICE_NAME(3) Library Functions Manual CURLOPT_SERVICE_NAME(3)
NAME
CURLOPT_SERVICE_NAME - authentication service name
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SERVICE_NAME, char *name);
DESCRIPTION
Pass a char pointer as parameter to a string holding the name of the
service for DIGEST-MD5, SPNEGO and Kerberos 5 authentication mechanisms.
The default service names are "ftp", "HTTP", "imap", "ldap", "pop" and
"smtp". This option allows you to change them.
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
