Hello all,
In my somewhat recent header wanderings I noticed that we have a resource.h in
private/kernel.
This header is entirely compatible and suitable for usage as the posix
sys/resource.h header. No
changes to the header need to be made, although the header should have some
additions to be
R5 & posix compatible. These are the additions:
1. add #include <sys/time.h>
2. add struct rusage
3. add getrusage prototype
It's my understanding that getrusage is public R5 and so we support it.
However, I realize that
this support will likely require kernel support, and a new syscall. (?) None
of our current source
exercises rusage functionality. (unsurprisingly)
I have been building with a modified and relocated resource.h for some time.
Here's my
proposal:
1. make the above additions to a copy of our resource.h
2. check it in at current/headers/posix/sys/resource.h
3. remove the existing current/headers/private/kernel/resource.h
Are there any comments or objections? BTW, the free bsd rusage has a lot more
fields than the
R5 rusage struct does. The R5 rusage struct contains only those mandated by
the posix spec, and
those are the only ones I was planning to add. (ru_utime, ru_stime)
