windows program. The data before OPOST-processing is written to
output_handle and OPOST-processing is applied in the master-side. For a
cygwin process, OPOST-processing is applied in the slave-side, and the
data after OPOST-processing is written to output_handle_cyg.

and forwards data from io_handle to to_master_cyg. Add function

between io_handle and to_master are used only by native windows program

through the data which is applied OPOST-processing in the slave-side.

handle to_master_cyg.

processed output. Create new thread to forward data from io_handle to
to_master_cyg. Set handle to_master_cyg to tty. Print io_handle_cyg as

get_handle().
* tty.h (class tty): Add variable _to_master_cyg to store a handle to
which OPOST-processed data is written. Add two functions,
