PSTAT FUNCTION
Name
pstat_getpmq()
- get information for a POSIX message queue
Synopsis
#include <sys/pstat.h>
int pstat_getpmq(
struct pst_pmqinfo *
buf,
size_t
elemsize,
size_t
elemcount,
int
index
);
Description
pstat_getpmq()
returns information specific to a particular POSIX message queue. There is one
instance of this context for each POSIX message queue on the system. For each instance requested, up to a
maximum of elemsize bytes of data is returned in the
pst_pmqinfo structures pointed to by buf. The
elemcount parameter specifies the number of
pst_pmqinfo structures that are available at buf to be
filled in. The index parameter specifies the starting index within the context of POSIX message queues.
PSTAT FUNCTION
Name
pstat_getproc() - get information for a process
Synopsis
#include <sys/pstat.h>
int pstat_getproc(
struct pst_status *
buf,
size_t
elemsize,
size_t
elemcount,
int
index
);
Description
pstat_getproc() returns information specific to a particular process. There is one instance of this
context for each active process on the system. For each instance requested, up to a maximum of elemsize
bytes of data is returned in the
pst_status structures pointed to by buf. The elemcount parameter
specifies the number of
pst_status structures that are available at buf to be filled in. The index param-
eter specifies the starting index within the context of processes. As a shortcut, information for a single pro-
cess can be obtained by setting elemcount to
0 and setting index to the PID of that process.
PSTAT FUNCTION
Name
pstat_getprocessor()
- get information for a processor
Synopsis
#include <sys/pstat.h>
int pstat_getprocessor(
struct pst_processor *
buf,
size_t
elemsize,
size_t
elemcount,
int
index
);
Description
pstat_getprocessor() returns information specific to a particular processor (the only processor on a
uniprocessor system). There is one instance of this context for each processor on the system. For each
instance requested, up to a maximum of elemsize bytes of data is returned in the pst_processor struc-
tures pointed to by buf. The elemcount parameter specifies the number of pst_processor structures
that are available at buf to be filled in. The index parameter specifies the starting index within the context
of processors.
