The type field pst_stream structure can be PS_STR_HEAD, PS_STR_MODULE or

PS_STR_DRIVER. The union val in pst_stream will represent the structures head, module, or

driver in the respective cases. If the flag PS_STR_ISACLONE is set in pst_flag for head, the field

pst_dev_seq in head represents the clone driver sequence number the stream.

pst_swapinfo

This structure describes per-swap-area information. Each structure returned describes one "pool"

of swap space on the system, either a block device or a portion of a file system. Header file:

_T_ULONG_T pss_idx; /* Index for further pstat() requests */

_T_ULONG_T pss_flags; /* flags associated with swap pool */

_T_ULONG_T pss_priority; /* priority of the swap pool */

_T_ULONG_T pss_nfpgs; /* # of free pages of space in pool */

union { /* block and fs swap differ */

struct __pss_blk Pss_blk; /* Block device Fields */

struct __pss_fs Pss_fs; /* File System Fields */

struct pss_reserved Pss_XX; /* reserved for union expansion */

} pss_un;

_T_ULONG_T pss_swapchunk; /* block size */

For more information, refer to header file vm_pstat_body.h. Flag values for pss_flags:

SW_ENABLED à 0x1

SW_BLOCK à 0x2

SW_FS à 0x4
