NAME
       umad_poll - poll umad

SYNOPSIS
       #include <infiniband/umad.h>

       int umad_poll(int portid, int timeout_ms);

DESCRIPTION
       umad_poll()  waits  up  to  timeout_ms  milliseconds for a packet to be
       received from the port specified by portid.  Once a packet is ready  to
       be  read,  the  function	 returns  0. After that the packet can be read
       using umad_recv().  Otherwise, -ETIMEDOUT is returned. Note  that  suc‐
       cessfully  polling  a  port  does  not  guarantee  that	the subsequent
       umad_recv() will be non blocking when several  threads  are  using  the
       same  port.  Instead, use a timeout_ms parameter of zero to umad_recv()
       to ensure a non-blocking read.

RETURN VALUE
       umad_poll() returns 0 on success, and a negative value on error as fol‐
       lows:
	-EINVAL	   invalid port handle or agentid
	-ETIMEDOUT poll operation timed out
	-EIO	   poll operation failed
