pst_ipcinfo
This structure describes the system-wide global System V IPC constants. These are typically
(currently) defined at boot time, but may become dynamic in future releases. Header file:

pst_lvinfo
This structure contains per-logical volume information. Each structure returned describes one
logical volume. Header file <sys/pstat/lv_pstat_body.h>
