_T_LONG_T psd_mpdcnt; /* # of (bad) memory pages deallocated */

_T_LONG_T psd_monarch_node; /* monarch logical node ID */
_T_LONG_T psd_node_cnt; /* number of nodes on the system*/
_T_LONG_T psd_dnlc_size; /* Size of DNLC */
_T_ULONG_T psd_dnlc_hits; /* DNLC Cache hits */

The following fields are obsolete and provided only for backward compatibility:
psd_cpu_time, psd_mp_avg_1_min[], psd_mp_avg_5_min[], psd_mp_avg_15_min[],
psd_mp_cpu_time[][]. Since the size of these arrays is hard-wired, there is no way to get
information about more than a fixed number of processors with the pstat_getdynamic() call.
Instead, pstat_getprocessor() should be used. It returns the same information and supports any
number of processors.
Macros for field validity check for struct pst_dynamic (member psd_valid) are:
PSD_VM à 0x1
PSD_AVM à 0x2
These bits will be cleared in psd_valid if the corresponding members psd_vm and psd_avm
overflow.
pst_fileinfo2
This structure describes per-file information. Each structure returned describes one open file a
process. Header file: <sys/pstat/vfs_pstat_body.h>

* of opened files. */
