int libssh2_channel_handle_extended_data2(LIBSSH2_CHANNEL *channel, int ignore_mode);
ignore_mode - One of the three LIBSSH2_CHANNEL_EXTENDED_DATA_* Constants.
LIBSSH2_CHANNEL_EXTENDED_DATA_NORMAL: Queue extended data for eventual
reading
LIBSSH2_CHANNEL_EXTENDED_DATA_MERGE: Treat extended data and ordinary
data the same. Merge all substreams such that calls to
libssh2_channel_read(3)
will pull from all substreams on a first-in/first-out basis.
LIBSSH2_CHANNEL_EXTENDED_DATA_IGNORE: Discard all extended data as it
arrives.
Change how a channel deals with extended data packets. By default all extended data is queued until read by libssh2_channel_read_ex(3)
