558 :: casting from C for bitwise or

Is there a better way than

tc2.c_oflag = casttcflag_t

to bitwise OR c unsigned int fields. tc2.c_oflag is a cuint from termios.h. The or operator does not seem to work on cuints or tcflag_t which is a c "typedef unsigned int". The code I have seems to work but is fragile since a C unsigned int may not always be 32bits.

(Deleted because it was unnecessarily complicated.)

import unsigned, use 'cuint' and 'or' and maybe a conversion (not a cast), be happy.

Thank you. I am not sure how I missed it but I didn't see the unsigned lib. Why do you want to discourage the use of unsigned?

Thanks Dom96. In C, I never used unsigned for anything except holding flags. That is what the termios library was using it for as well. I'll use signed ints in nimrod just because I am lazy.
