php_ini_scanned_files is not defined

[Majkl578]

On HHVM 3.2.0:

$ hhvm --php -r 'php_ini_scanned_files();'
Fatal error: Call to undefined function php_ini_scanned_files() in /tmp/php-wrap-zyqILs on line 2

The behavior should match php's behavior which is as follows:

Returns a comma-separated string of .ini files on success. Each comma is followed by a newline. If the directive --with-config-file-scan-dir wasn't set, FALSE is returned. If it was set and the directory was empty, an empty string is returned. If a file is unrecognizable, the file will still make it into the returned string but a PHP error will also result. This PHP error will be seen both at compile time and while using php_ini_scanned_files().

So in the context of HHVM, it should probably always return FALSE.
