This function polls on all file descriptors used by the curl easy handles
contained in the given multi handle set. It will block until activity is
detected on at least one of the handles or \fItimeout_ms\fP has passed.
\fIcurl_multi_wait(3)\fP polls all file descriptors used by the curl easy
handles contained in the given multi handle set. It will block until activity
is detected on at least one of the handles or \fItimeout_ms\fP has passed.
Alternatively, if the multi handle has a pending internal timeout that has a
shorter expiry time than \fItimeout_ms\fP, that shorter time will be used
instead to make sure timeout accuracy is reasonably kept.
