From: nccc on 31 Oct 2009 11:34 Hi all I have some trouble with the very internals of Solaris on UltraSPARC III. The problem is that I need access to the proc_t struct of the process whose thread is executing on a processor. Can proc_t for the running thread/process or a pointer to it be found somewhere in the process address space? Thanks, nccc

I need the pid and the path to the executable file on the disk. Please note that I cannot execute code on the machine, because it is running under a simulator (simics). I have to retrieve this information by merely looking into the process address space.
From: nccc on 31 Oct 2009 17:07 Anyway, if there is no way to find this information in the process address space, where exactly can I find it in the kernel memory? Is there a fixed position for the proc_t of the active process or for a pointer to it? Thanks

It is possible only from kernel address space. Is the simulator stopped when you look at the kernel? Casper -- Expressed in this posting are my opinions.
