OpenVMS getdtablesize.c and getloadavg.c issues.

[John E. Malmberg]

Hello,

The getdtablesize.c module will not compile on OpenVMS and is really not 
needed.

The way that the an OpenVMS getrlimit() would be most likely implemented 
to return the RLIMIT_NOFILE is to call the system supplied getdtablesize().

Is there someway for configure to be changed to not set the macros 
causing it to be built when the platform is OpenVMS?

The dtablesize is fixed at the time that the image is run as it is the 
lesser of the SYSGEN channelcnt setting and the user's fillm quota.

There is no API to adjust it for a running process.


The getloadavg.c OpenVMS code probably has not built in quite some time 
and probably for now should be reduced to setting the ENOSYS errno and 
returning -1.

It has two variants, one requires the long gone eunice product, and the 
other requires a third party LOADAVERAGE driver that I can not find any 
current download location for.

From OpenVMS 7.3 on, the sys$getrmi() system service is used to return 
that information, and I will look at writing that code at a future time.

Regards,
