NAME

     libssh2_session_block_directions - get  directions  to  wait
     for

SYNOPSIS

     #include <libssh2.h>

     int  libssh2_session_block_directions(LIBSSH2_SESSION  *ses-
     sion);

DESCRIPTION

     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 avail-
     able for reading or writing. Depending on the  return  value
     of libssh2_session_block_directions(3) an application should
     wait for read, write or both.

RETURN VALUE

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

     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_OUTBOUND writefds set  should  con-
     tain the socket.
