I believe EMX was earlier than that. That's what
I used.

I have 3 different 32-bit interfaces that could
be suitable for integrating into DOS (Freedos I
guess). Do you have something specific in mind?

Would you be happy if the DOS interrupts thunked
to 32-bit counterparts? I assume you're not happy
to switch to 32-bit-only apps?

Did you mean 1985?

Regardless, no, I was talking about ISO/IEC 9899:1990
aka C90.

The wrapper I showed you did an INT 21H. I don't
know what alternative you could possibly be
suggesting.

In my OS at least (both PDOS/86 and PDOS/386),
that wrapper has an identically-named function
in the main OS source file, waiting to service
that call. I don't see how it can get any
OS-ier than that.
