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