Perhaps some of the "pstat_static" stuff will talk about RAM. Perusal
of the pstat include file(s) might find it. Otherwise, at the risk of
it doing "something else" you could try the latest PD top sources
and/or a tusc (aka system call) trace of top running on an HP-UX
system (or of vmstat or other tools I suppose...)

Yeah -- I tried to point him at pstat() in comp.lang.c, but I guess that
didn't get read.

[Rick, this is directed at k.szczesny -- not at you.. ;) ]
What you want is some combination of pstat_getvminfo(),
pstat_getstatic() and pstat_getdynamic(). Exactly what usage depends
on exactly what you want... read "man 2 pstat" to find out where the
headers live, and check the fields and their descriptions for the
structures filled in by those.

If all you want is total RAM on the machine, and total RAM in
use [by kernel + user + firmware + bad pages, etc.],
physical_memory is in the pst_static structure [total RAM],
and psd_free in the pst_dynamic structure is your free RAM -
both should be in pages, I believe. Per-process RAM usage,
virtual memory consumption, swap and the like will take more
fields/calls.

More arcane machine-dependent things such as CPU types, hardware
bits and the like are best found via the sysconf interface.
"man 2 sysconf"

Take a look -- and feel free to follow up if you have specific
questions.

Thank You Don,

that helped a lot.

My library is done, all i have to do is make it work with java.
On windows there was no problem, but on hp-ux it just can't see the
library, though it's in a directory defined in java.library.path.

Best regards to all,
thank You for help,

Krystian

It's solved!
Thanks to Gordon Beaton from comp.lang.java.programmer.
He did same example file as I did, and run it with strace /i can't/.
java searches for lib+filename_from_application+.sl file, so i had to
rename my uxinfo.sl to libuxinfo.sl and now it works - well... at least
it loads the library! :)

Best regards, and thanks to all,
Krystian
