       libssh2_session_block_directions  -  get  directions that socket should
       wait for before calling libssh2 function again


       #include <libssh2.h>

       int libssh2_session_block_directions(LIBSSH2_SESSION *session);


       session - Session instance as returned by libssh2_session_init_ex(3)

       When  any  of  libssh2   functions   return   LIBSSH2_ERROR_EAGAIN   an
       application  should  wait  for  the  socket  to have data available for
       reading   or   writing.   Depending   on   the    return    value    of
       libssh2_session_block_directions(3)  an  application  should  wait  for
       read, write or both.


       Returns the set of directions as a binary mask. Can  be  a  combination

       LIBSSH2_SESSION_BLOCK_INBOUND: Inbound direction blocked.

       LIBSSH2_SESSION_BLOCK_OUTBOUND: Outbound direction blocked.

       Application  should  wait  for data to be available for socket prior to
       calling a libssh2 function again. If  LIBSSH2_SESSION_BLOCK_INBOUND  is
       set   select   should  contain  the  session  socket  in  readfds  set.
       Correspondingly in case of LIBSSH2_SESSION_BLOCK_INBOUND  writefds  set
       should contain the socket.
