NAME

       libssh2_session_block_directions - get directions to wait for

SYNOPSIS

       #include <libssh2.h>

       int
       libssh2_session_block_directions(LIBSSH2_SESSION *session);

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 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.

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 contain the socket.
