61 * KERN_PROC subtype ops return arrays of selected proc structure entries:
62 *
63 * When adding new fields to this structure, ALWAYS add them at the end
64 * and decrease the size of the spare field by the amount of space that
65 * you are adding. Byte aligned data should be added to the ki_sparestring
66 * space; other entries should be added to the ki_spare space. Always
67 * verify that sizeof(struct kinfo_proc) == KINFO_PROC_SIZE when you are
68 * done. If you change the size of this structure, many programs will stop
69 * working! Once you have added the new field, you will need to add code
70 * to initialize it in two places: kern/kern_proc.c in the function
71 * fill_kinfo_proc and in lib/libkvm/kvm_proc.c in the function kvm_proclist.
72 *
73 * KI_NSPARE is the number of spare-longs to define in the array at the
74 * end of kinfo_proc. It may need to be overridden on a platform-specific
75 * basis as new fields are added.
