New Data Structures

The following are new data structures being added to the PSTAT

module:

pst_fileinfo2 Describes per-ﬁle information. For the

speciﬁed process, there is one instance of this

context for each open ﬁle descriptor.

pst_fid Used to efﬁciently re-access the opened ﬁles.

This value is returned by

pstat_getfile2(), pstat_getproc(),

and pstat_getprocvm() calls. This ID is

then passed to subsequent PSTAT calls such

as pstat_getsocket() to efﬁciently

re-access the opened ﬁles.

pst_filedetails This data structure contains detailed

information speciﬁc to a particular open ﬁle.

For a speciﬁed ﬁle, there is only one instance

of this structure. This information includes

stat equivalent information.

pst_socket The PSTAT socket structure contains detailed

information pertaining to an opened socket,

such as type, state, protocol, address family,

and options of the socket. For a speciﬁed

socket, there is only one instance of this

structure.

pst_stream The PSTAT stream structure contains

detailed information pertaining to a stream

entity. This includes information about the

head, names of modules pushed, and the

driver of the stream.
