Wrapper Function Descriptions
pstat_getcommandline()
Returns the commandline of the process specified in the pid parameter. Up to a max-
imum of elemsize - 1 bytes are returned in the buffer buf, if the
elemsize is less
than or equal to the size of the process commandline. If the
elemsize is greater than the
size of process commandline, only the available number of bytes are returned. Up to a
maximum of 1020 characters of the process commandline is stored. The elemcount
parameter has to be one.
pstat_getcrashdev()
Returns information specific to a particular crash dump device. There is one instance of
this context for each crash dump device configured on the system. For each instance
requested, data, up to a maximum of elemsize bytes, is returned in the structs
pst_crashdev pointed to by buf. The elemcount parameter specifies the number of
structs pst_crashdev that are available at buf to be filled in. The index parame-
ter specifies the starting index within the context of crash dump devices.
pstat_getcrashinfo()
Returns information about the system’s crash dump configuration. Data, up to a maximum
of
elemsize bytes, are returned in the struct pst_crashinfo
pointed to by buf.
The
elemcount parameter must be 1. The index parameter must be 0.
pstat_getdisk()
Returns information specific to a particular disk. There is one instance of this context for
each disk configured into the system. For each instance requested, data, up to a maximum
of
elemsize bytes, is returned in the structs pst_diskinfo pointed to by buf.
The elemcount parameter specifies the number of structs pst_diskinfo that are
available at buf to be filled in. The index parameter specifies the starting index within
the context of disks.
pstat_getdynamic()
Returns dynamic information about the system. There is one global instance of this con-
text. Data, up to a maximum of elemsize bytes, is returned in the struct
pst_dynamic
pointed to by buf. The elemcount parameter must be 1. The index
parameter must be 0.
pstat_getfile()
This call is now obsolete and is provided for backward compatibility only. Use of
pstat_getfile2() call is recommended. Returns information specific to a particular
