+.SH NAME
+curl_multi_select - polls on all easy handles in a multi handle
+.SH SYNOPSIS
+.nf
+#include <curl/curl.h>
+
+CURLMcode curl_multi_wait(CURLM *multi_handle,
+ struct curl_waitfd extra_fds[],
+ unsigned int extra_nfds,
+ int timeout_ms);
+.ad
+.SH DESCRIPTION
+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.
+
+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.
+
+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.
+.SH curl_waitfd
+.nf
+struct curl_waitfd {
+ curl_socket_t fd;
+ short events;
+ short revents;
+};
+.fi
+.IP CURL_WAIT_POLLIN
+Bit flag to curl_waitfd.events indicating the socket should poll on read
+events such as new data received.
+.IP CURL_WAIT_POLLPRI
+Bit flag to curl_waitfd.events indicating the socket should poll on high
+priority read events such as out of band data.
+.IP CURL_WAIT_POLLOUT
+Bit flag to curl_waitfd.events indicating the socket should poll on write
+events such as the socket being clear to write without blocking.
+.SH RETURN VALUE
+CURLMcode type, general libcurl multi interface error code. See
+\fIlibcurl-errors(3)\fP
+.SH AVAILABILITY
+This function was added in libcurl 7.28.0
