Is adding a pthread wrapper for sched_{get,set}attr feasible?

[Juri Lelli <juri dot lelli at redhat dot com>]

Hi all,

During a recent discussion on linux-rt-users mailing list [1] was
pointed out that adding a pthreads wrapper around sched_{get,set}attr
syscalls would make life a little easier (and code cleaner?) for users
of such interface.

One can of course easily use the interface by doing gettid() and calling
syscall() - e.g., [2] - but properly supporting the same interface in
standard libraries might be to prefer, as it would also align with the
existing pthread_attr_setschedparam(), etc.

I researched a bit the archives, but couldn't find anything related to
this question. Any pointers? Any thoughts about the feasibility of
adding such support?

Thanks!

Best,

- Juri
