Hi Sergei
Thanks for the notes. I tried to extend this concept to tty.c, please
see attached CDL. Here are my questions.
1. The proc output is in io-serial.h and is protected to instantiate in
only file that defines __CYGSEM_FILE_IS_IO_SERIAL_COMMON_TTY_C (tty.c)
I would ask if it is possible to redirect puts to other file?
2. This may be question for John.
CYGOPT_IO_SERIAL_PROC_INCREMENTER interface is used as a stealth
container for define_proc.
I guess this is not a typical usage of cdl_interface. Could it cause a
trouble?
Note: I haven't tested compilation yet, only header generation. If this
approach is considered acceptable I would produce required changes in
tty.c and post a bug on Bugzilla.
Regards
Ilija
