Hi - I'm on my continuing saga of doing kernel level rerouting, when I came around to a related question. Essentially, I have these types for variables whose definitions I cannot find. Where is proc defined? Where is register_t defined? What are they used for?

struct proc *p

register_t *retva


Thanks,

You'd have to look in the header files for a definition. proc is a C struct. register_t is a type.

register_t is defined in /usr/includes/ppc/types.h as int32_t, which in turn is defined as an int.

proc is defined in /usr/includes/sys/proc.h. I was going to post it here, but it is quite a large structure. Instead I will just post this description from the .h file:

Code:
/*
 * Description of a process.
 *
 * This structure contains the information needed to manage a thread of
 * control, known in UN*X as a process; it has references to substructures
 * containing descriptions of things that the process uses, but may share
 * with related processes.  The process structure and the substructures
 * are always addressible except for those marked "(PROC ONLY)" below,
 * which might be addressible only on a processor on which the process
 * is running.
