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

551 * miscellaneous kinfo structures to sbuf. The main consumers are KERN_PROC
552 * sysctls but they may also be used by other kernel subsystems.
554 * The functions manipulate the process locking state and expect the process
555 * to be locked on enter. On return the process is unlocked.
