Hi,

I'm writing a piece of time critical code for a T222. One thing
that I would like to do is for a process to be able to see if
there are other processes waiting to be executed on the scheduling
list.  In the literature this is referred to as the "FRONT POINTER",
but I haven't been able to find out how to get access to it.

What I'm looking for is the opposite of the "STHF" instruction.

Can anyone help me?

Thank you for any help,

Tomas


PS.  If somebody can tell me something about exactly when processes
are moved from the "time waiting queue" to the list of processes to
be executed, that would also be very helpful.
