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
