CURLOPT_SERVICE_NAME - authentication service name

Added in curl 7.43.0

See above

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.

int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode ret; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); curl_easy_setopt(curl, CURLOPT_SERVICE_NAME, "custom"); ret = curl_easy_perform(curl); } }
