This function polls on all file descriptors used by the curl easy handles
@@ -39,6 +40,9 @@ detected on at least one of the handles or \fItimeout_ms\fP has passed.
The calling application may pass additional curl_waitfd structures which are
similar to \fIpoll(2)\fP's pollfd structure to be waited on in the same call.
+On completion, if \fIret\fI is supplied, it will be populated with the
+number of file descriptors on which interesting events occured.

This function is encouraged to be used instead of select(3) when using the
multi interface to allow applications to easier circumvent the common problem
with 1024 maximum file descriptors.
