PSTAT Interfaces

uint32_t pst_pstate; /* protocol state */

_T_ULONG_T pst_boundaddr_len; /* Length of pst_boundaddr */

_T_ULONG_T pst_remaddr_len; /* Length of pst_remaddr */

char pst_boundaddr[PS_ADDR_SZ]; /* local addr/port, etc */

char pst_remaddr[PS_ADDR_SZ]; /* peer addr/port, etc */

The members pst_boundaddr and pst_remaddr contain data of the form struct sockaddr,

sockaddr_un, sockaddr_in, sockaddr_in6, etc. depending on the socket family. In case of

AF_UNIX sockets, pst_peer_hi_nodeid and pst_peer_lo_nodeid fields can be used to find the peer

socket by matching them with pst_hi_nodeid and pst_lo_nodeid of the other sockets.

pst_stable

This structure describes the information in any system's stable storage area. Header file:

_T_LONG_T pss_size; /* Number of bytes of stable store */

_T_LONG_T pss_type; /* Type of stable store */

_T_LONG_T pss_pad[8]; /* Reserved */

union {

unsigned char Pss_PA_RISC_buffer[PST_MAX_PA_RISC_STABLE];

/* Uninterpreted stable store data */

struct pst_stable_PA_RISC Pss_PA_RISC_stable;

/* PA-RISC stable store data */

} pss_un;

For more information, refer to mdep_pstat_body.h file.

Values for pss_type: PS_PA_RISC à 0x1 /* PA-RISC stable store */

Max bytes in a PA-RISC stable store area: PST_MAX_PA_RISC_STABLE à 256

pst_static

This structure contains static system information -- data that will remain the same (at least) until

reboot. Header file: <sys/pstat/global_pstat_body.h>
