This changes from `FASYNC` to `O_ASYNC`, `FNDELAY` to `O_NONBLOCK`, and `O_NDELAY` to `O_NONBLOCK`. These are the modern names. `O_NONBLOCK` is part of the POSIX standard. However, `O_ASYNC` is specific to Linux and BSD. It is not available on Solaris, where we still need to use `FASYNC`. Also, the behavior of having I/O trigger a `SIGIO` signal is not in POSIX, since the `SIGIO` signal is not in POSIX. Instead, it is only the behavior of having `SIGURG` being signalled for out of band data that is specified. We also takes this opportunity to collapse some multi-line calls to get the flags, store it into a temp, and then set them, to just doing it in one line, skipping the stored temporary value. We also change one instance of `65535 - FNDELAY` to `~O_NONBLOCK`. Closes interlisp/medley#85.
Maiko
This is the implementation of the Medley Interlisp virtual machine, for a byte-coded Lisp instruction set and some low-level functions for connecting with Lisp for access to display and disk etc.
There are make file fragments that include all the flags and variables you have to set for each hardware/OS target.
- cd to the "bin" directory
- have "." on your PATH
- do "./makeright x"
It will (attempt to) detect the OS-type and cpu-type, and put together the makefile parts that it needs. It will build in ../ostype.cputype-x (for the .o files) and ../ostype.cputype for the executables.
Development Platforms
We are developing on FreeBSD, Linux, macOS, and Solaris currently on arm, arm64, PowerPC, SPARC, x86, and x86_64 hardware.
We believe it will work on these platforms.
Fixes and improvements for additional platforms and hardware is welcome. Work is underway to run better on Windows.
In the past, Maiko ran on DOS. This may or may not still work.
