They have been asked this question a thousand times and have exactly the information you are requesting. The interface was initially not documented because it wasn't to be used by user applications. Obviously user's think it is useful, so they are using it ;-) Actually, if you have the process ID you have the slot number that the (struct proc) is in. You can take that number and use it as an offset into the process table and read the entire structure yourself. Of course that's very unportable ...

After a lot of begging , pleading I got a copy of the man page for this faxed to me. But the person who faxed it to me made very clear that 1) the call is not supported (ie. use at your own risk) and 2) the call may not survive long in AIX 3.1.?????

But the person >who faxed it to me made very clear that 1) the call is not supported (ie. >use at your own risk) and 2) the call may not survive long in AIX 3.1.????? Please don't make the assumption that the system call or the system call interface will "be around for [a] long" time. That is exactly the reasoning I was given when I requested permission initially to release the getprocinfo() interface information. The reason for keeping the interface "unsupported" is to allow development to change the interface for whatever reasons they may come up with. Without giving examples, it is possible that a more/better/different interface may be dreamt up at some point in the future, and having it be a "supported" interface would prevent any non-compatible changes from being made. So, use it at your own risk - and let IBM know that you find the system call useful, so they will be encouraged to begin supporting it. This is the kind of feedback IBM likes to hear.
