libssh2_session_block_directions - get directions to wait for
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 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.
