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.
