Hello,
Additional POSIX realtime (POSIX 1003.1b) support has been added:
1) MQueue.hsc - POSIX message queues
Supported FFI bindings for:
- mq_open
- mq_close
- mq_unlink
- mq_getattributes
- mq_setattributes
- mq_send
Not yet supported bindings:
- mq_rcv .. still debugging a mysterious problem
- mq_notify - will support when asynchronous I/O is implemented
2) RTsched.hsc - real time scheduling
Supported bindings for:
- sched_yield
- sched_get_param
- sched_set_param
- sched _get_scheduler
- sched_set_scheduler
- sched_get_priority_min
- sched_get_priority_max
Unsupported currently:
- sched_rr_get_interval - still looking for the TimeSpec data type in order to get "peek" working
3) Files.hsc
Added bindings for:
- fsync
- fdatasync
I am new to Haskell but would like to make a lot of contributions to insure Haskell success in the marketplace (of ideas ;^)). I apologize for any glitches and look for feedback.
Very interesting! However... this library is a core package, and maintained by libraries@haskell.org, so you should not release it yourself. Instead, submit your patches to libraries@ for inclusion, following the patch submission guide here: http://haskell.org/haskellwiki/How_to_write_a_Haskell_program Where the patches will be tested on other unix platforms, and then encorporated into the main 'unix' repository. Also, as unix .hsc files tend to be a bit fragile, portability wise, it might be a good idea to instead place your patches in a separate library on hackage, rather than patching the 'unix' package directly. We have many other unix-alike packages, so one for message queues, and real time scheduling make sense -- separate from the core 'unix' package (like the mmap package, for example). -- Don
