Sorry, not sure I understand.

Neither of those scenarios is an error, so curl_multi_info_read()
returns NULL when called right after curl_multi_exec() as show below:

$mc_handle = curl_multi_init();
$c = curl_init();
// Set up the handle and options
curl_multi_add_handle($mc_handle, $c);
do {
    $cme = curl_multi_exec($mc_handle, $remain);
} while ($cme == CURLM_CALL_MULTI_PERFORM);
$rc = curl_multi_info_read($mc_handle); // This returns FALSE i.e.
NULL from the C library both when the connection was successful and
when it is still waiting.

Neither curl_multi_wait() nor the 'older' function curl_multi_fdset()
exposes whether the internal file descriptor is ready for writes
(indicating a successful connection).
