libssh2_poll - poll for activity on a socket, channel or listener

       This  function  is  deprecated.  Do  note use. We encourage users to instead use the poll(3) or select(3)
       functions to check for socket activity or when specific sockets are ready to get received  from  or  send
       to.

       Poll  for  activity  on a socket, channel, listener, or any combination of these three types. The calling
       semantics for this function generally match poll(2) however the structure of fds is somewhat more complex
       in order to accommodate the disparate datatypes, POLLFD constants have been namespaced to avoid  platform
       discrepancies, and revents has additional values defined.
