docs/libcurl/opts: clarify the return values
Expand a little.

- mention the type name of the return code
- avoid stating which exact return codes that might be returned, as that
  varies over time, builds and conditions
- avoid stating some always return OK
- refer to the manpage documenting all the return codes

# NAME
CURLOPT_SERVICE_NAME - authentication service name
# SYNOPSIS
~~~c
#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
See above
# %PROTOCOLS%
# EXAMPLE
~~~c
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);
}
}
~~~
# %AVAILABILITY%
# RETURN VALUE
curl_easy_setopt(3) returns a CURLcode indicating success or error.

libcurl-errors(3).
