/*

|
* KERN_PROC subtype ops return arrays of selected proc structure entries:
|
|
*
|
|
* This struct includes several arrays of spare space, with different arrays
|
|
* for different standard C-types. When adding new variables to this struct,
|
|
* the space for byte-aligned data should be taken from the ki_sparestring,
|
|
* pointers from ki_spareptrs, word-aligned data from ki_spareints, and
|
|
* doubleword-aligned data from ki_sparelongs. Make sure the space for new
|
|
* variables come from the array which matches the size and alignment of
|
|
* those variables on ALL hardware platforms, and then adjust the appropriate
|
|
* KI_NSPARE_* value(s) to match.
|
|
*
|
|
* Always verify that sizeof(struct kinfo_proc) == KINFO_PROC_SIZE on all
|
|
* platforms after you have added new variables. Note that if you change
|
|
* the value of KINFO_PROC_SIZE, then many userland programs will stop
|
|
* working until they are recompiled!
|
|
*
|
|
* Once you have added the new field, you will need to add code to initialize
|
|
* it in two places: function fill_kinfo_proc in sys/kern/kern_proc.c and
|
|
* function kvm_proclist in lib/libkvm/kvm_proc.c .
