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