| 2015 |
Job/session number (I32) Put: No; Verify: Yes; Release 3.0
Returns the job/session number of the job/session domain to which the
process belongs. This number is valid for processes of the type user and
son. For all other processes, a 0 is returned. It also returns a 0 for
some user processes like VTSERVER and NFT. A negative number indicates a
job; a positive number indicates a session. The job/session number for
this job or session in the following format:
| Bits (0:2) | Job or session? ( 1 = Session, 2 = Job ) |
| Bits (2:14) | Number |
| Bits (16:16) | Extension |
|
| 2016 |
Scheduling state (I32) Put: No; Verify: Yes; Release 3.0
Returns the state of the process, as viewed by the dispatcher. It is the
first item that should be interrogated to ascertain a process's state.
Values and their meanings are as follows:
| 0 | Executing (only for Calling Process) |
| 1 | Ready |
| 2 | Short wait |
| 3 | Long wait |
| 4 | Null |
Processes in the ready queue are linked together in the order of priority.
A short wait is basically a wait for disk I/O, and the dispatcher expects
the process to be ready in a short while. See the item 2025 "Reason for
waiting" for further information. The null state is seen only for
processes that are dead or in the process of dying. |
| 2017 |
Scheduling queue (I32) Put: Yes; Verify: Yes; Release 3.0
Returns or modifies the scheduling queue that this process belongs to.
Values and their meaning are as follows:
| 0 | AS Queue |
| 1 | BS Queue |
| 2 | CS Queue |
| 3 | DS Queue |
| 4 | ES Queue |
Modifying this information causes the process to be placed in the
specified queue, with the priority being the base of the new
queue. |
| 2018 |
Degradable priority? (B) Put: Yes; Verify: Yes; Release 3.0
Returns or modifies whether the process undergoes priority decay. True
indicates that the process will undergo the normal priority decay from
base to limit to base of the scheduled class it is in (CS, DS, ES), while
it is in a circular queue. False causes the priority to remain fixed at
the current priority. Classes are obtaining through AIFSCGET.
This item makes sense only for processes in the circular classes (CS, DS,
ES) since the linear queue processes do not undergo priority decay. Also,
a process that has gone through decayable boosting is always subject to
priority drop. This also means that it contributes towards the system
CS-SAQ.
Scheduling classes can be obtained through AIFSCGET. |
| 2019 |
Priority (I32) Put: Yes; Verify: Yes; Release 3.0
Returns or modifies the priority of the process. This is an MPE/iX
priority. It is very transient for user processes. For processes whose
priority is not fixed, this value should be interpreted as the priority at
which the process was last dispatched. For nonconstant priority processes,
it is not used in determining the priority at which it will be dispatched
next.
A valid MPE/iX priority is in the range 0..32767. The new priority should
be in the range of priorities specified by the base and the limit of the
current scheduling class of the process. This priority can be mapped to
MPE V by the following formula:
(All formula values are decimal)
MPEVPri = (32767 - MPEXLPri) DIV 128
ex. B149 = (32767 - 13695) DIV 128
|
| 2020 |
Reasons for boost (U32) Put: No; Verify: Yes; Release 3.0
Returns the reasons for the priority boost. The bits and their meanings
are as follows:
| Bit (0:1) | The process is experiencing a non-decayable
boost because the process owns a priority
semaphore or resource for which there is a
contention. |
| Bit (1:1) | The process is experiencing a non-decayable
boost because the process owns a SIR for
which there is a contention. |
| Bit (2:1) | The process is experiencing a non-decayable
boost because the process has a long-running
system transaction. |
| Bit (3:1) | The process is experiencing a non-decayable
boost to ensure prompt handling of a system
or subsystem break event. |
| Bit (4:1) | The process is experiencing a decayable
boost because the process owns a priority
semaphore or resource for which there is
contention. |
| Bit (5:1) | The process is experiencing a non-decayable
boost because the process is currently
deemed unpreemptable and has blocked. |
| Bit (6:1) | The process is experiencing a non-decayable
boost because the process is hosting a IPC
server for which there is contention. |
| Bit (7:1) | The process is experiencing a decayable
boost because the process has a long-running
user transaction. |
| Bit (8:1) | The process is experiencing a non-decayable
boost because the process owns a priority
semaphore port for which there is
contention. |
| Bit (9:1) | The process, a serial printer server, is
experiencing a decayable boost to force
priority oscillation. |
If no bit is turned on, the process priority has not been boosted. |
| 2021 |
Post boost priority (I32) Put: No; Verify: Yes; Release 3.0
Returns the post boost priority of the process. This is an MPE/iX priority
with a range of 0..32767. This is the priority that will be in effect
after the process has unboosted from a new priority to which it was
boosted for some purpose. The process will be reassigned this priority as
soon as possible. A 0 is returned if the process is not currently
boosted. |
| 2022 |
Process state (I32) Put: No; Verify: Yes; Release 3.0
Returns the state of the process from the viewpoint of process management.
In general, it should be alive for most processes. The other states are
generally very transient. The data returned is valid mainly for the alive
case. Values and their meanings are as follows:
| 0 | Unknown |
| 1 | Dying |
| 2 | Dead |
| 3 | Alive |
| 4 | Initiate |
| 5 | Unborn |
|
| 2023 |
Time in ticks, when it began waiting (REC) Put: No; Verify: Yes;
Release 3.0
Returns the time, in ticks, since 1970 when the process entered the wait
state. This field is only updated when the Measurement Interface is turned
on. This time is processor dependent. To obtain processor-independent time,
use the item 2024 for time in milliseconds. (This item provides faster
access to time than item 2024.)
Record type: longint_type (Refer to appendix B.) |
| 2024 |
Time in milliseconds, when it began waiting (REC) Put: No; Verify: Yes;
Release 3.0

Returns a list of fully qualified file names of the files opened by this
process. The file name, group name, and account name are each
left-justified and padded with blanks. For device files and standard files,
the group and account names will be blanks.
Only those names which can be represented by MPE-syntax will be returned.
For HFS files, the filename, group, and account fields will be blank and a
warning will be returned. Your application can either check for blank
names if you wish to continue using this item or you can use item 2122 to
retrieve the file pathnames.
The maximum number of files that can be opened by a process can be
obtained from AIFSCGET. You should pass an area of appropriate
size. The first word of the buffer is expected to hold the size, in
16-byte records, of the rest of the buffer area. The first word, on return,
specifies the number of names returned. Check
itemstatus_array to see if information was truncated.
Record type: Fnamerec_type (Refer to appendix B.) |
| 2065 |
UFIDs of files (REC) Put: No; Verify: No; Release 3.0
Returns a list of UFIDs (unique identifiers) for the open files. These can
then be used as input to the other AIFs. For device files and standard
files, the UFID will be blanks. You should pass an area of appropriate
size. The first word of the buffer will be expected to hold the size, in
5-word chunks, of the rest of the buffer area. The first word, on return,
specifies the number of UFIDs returned. Check
itemstatus_array to see if information was truncated.
The Pathname Identifier, item 2123, should be specified for HFS files
since the UFID alone is not adequate to return a Pathname for an HFS file.
Record type: Ufidrec_type (Refer to appendix B.) |
| 2066 |
Process Tree (REC) Put: No; Verify: No; Release 3.0
Returns entire process tree, PIDs for calling process, PIDs for children,

|
| 2070 |
General resource capabilities (U32) Put: Yes; Verify: Yes;
Release 3.0
Returns or modifies the resources capability mask for the process. This
mask contains the resource capabilities for the user associated with the
process. Not valid for processes in the wait state. Mask bits and their
meanings are as follows:
| Bits(0:22) | Unused |
| Bit (23:1) | Batch access |
| Bit (24:1) | Interactive access |
| Bit (25:1) | Privileged mode |
| Bit (26:2) | Unused |
| Bit (28:1) | Multiple RINs |
| Bit (29:1) | Unused |

Number of CM intrinsic errors (I32) Put: Yes; Verify: Yes;
Release 3.0
Returns or modifies the number of errors during the last call to a CM
intrinsic. Values are in the range 0..6. This item is zeroed out upon
entry into a CM intrinsic. |
| 2074 |
CM intrinsic errors (I32A) Put: Yes; Verify: No; Release 3.0
Returns or modifies the errors dumped onto the stack by the last call to a
CM intrinsic. It is flushed out upon entry to any intrinsic. Values are in
the range of shortint.
The highest index entry is the last error recorded. The format of the
error message depends upon the intrinsic called. This array can have a
maximum of 6 elements. You should pass an area of appropriate size. The
first word of the buffer is expected to hold the size, in words, of the
rest of the buffer area. The first word, upon return, specifies the number
of error returned. Check itemstatus_array to see if
information was truncated. |
| 2075 |
Last FOPEN error (I32) Put: Yes; Verify: Yes; Release 3.0
Returns or modifies the last FOPEN error in accessing a file.
Prior to Release 4.5, valid values for this item were in the range 0..255.
Now because there is an increase in the number of errors the file system
must report, the last FOPEN error is kept in the form of an HPE status in
a process structure. This HPE status gets converted to an MPE error when
the user calls FCHECK.
Therefore, when getting this item, the HPE status will be converted to an
MPE error, and on a PUT, the MPE error will be converted to a HPE status.
This is to maintain compatibility for existing applications. Currently, if
you pass in an invalid FOPEN error which cannot be converted, the file
system will return an FOPEN error of -20 (Invalid Operation). |
| 2076 |
Last KOPEN error (I32) Put: Yes; Verify: Yes; Release 3.0
Returns or modifies the last KOPEN error in accessing a KSAM file.
It is a CM KOPEN error status. Values are in the range 0..255.

Pathnames of Open Files (@64) Put: No; Verify: No; Release 4.5
Returns a list of file pathnames for each file opened by this process. The
long pointer specified in this item points to the buffer where the names
will be returned. Each name will be terminated by a NULL character.
On input, the first four bytes in the buffer will represent the maximum
buffer length in bytes. On output, the first four bytes will contain the
actual number of bytes returned (this includes the NULL terminators
separating each name). Refer to Operation Notes for AIFSYSWIDEGET
for a diagram of the buffer format.
If an HFS file has been opened by UFID and not by name or if the file is a
special MPE file which cannot be represented as an HFS pathname (for
example, $TEMPDIRC), then there will be no pathname associated with the
file. In this case, a NULL character will be written to the buffer to
delimit a place holder for the file. This is so that each name will match
up with a corresponding entry in the file number and path_identifier
arrays (items 2063 and 2123).
See the buffer_type declaration in appendix B for a suggestion on how to
define this buffer. |
| 2123 |

Returns the unique path identifiers for the open files. If a file has been
opened by UFID and not by name or if the file is a special MPE file not
supported by the hierarchical directory services, then the path_identifier
entry for that file will not contain all the information needed to
identify a unique pathname. The parent_ufid and link ID fields will be
0.
Record type: path_id_rec_type |

Returns the process' real group ID. This POSIX attribute describes the
group a process belongs to. |
| 2129 |
EGID - Effective GID (I32) Put: Yes; Verify: Yes; Release 4.5
Returns the process' effective Group ID. This is a POSIX attribute which
determines access rights of a process to files. At process creation time,
the EGID matches the GID, but it may be changed with the setgid()
function. |
| 2130 |
CMASK (U32) Put: Yes; Verify: Yes; Release 4.5
Returns the process' file creation mask. This mask changes with the POSIX
umask() function. Any file created after a process calls umask
will have an ACD attached to the file. |
| 2131 |
Program pathname (REC) Put: No; Verify: Yes; Release 4.5
Returns the absolute pathname of the program file.
On input, the first four bytes in the buffer will represent the maximum
buffer length in bytes. On output, the name will be terminated by a NULL
character and the first four bytes will contain the actual number of bytes
returned (not including the NULL character or the one word length).
Note that this item should only be used for names that can be expressed
using HFS syntax. If you specify this item for a program (for example,
$OLDPASS) that cannot be expressed using HFS syntax, then a warning is
returned in itemstatus_array.
Record type: pathname_type |
| 2132 |
Break Request Done (B) Put: No; Verify: Yes; Release 4.5
Returns the Boolean flag used to indicate whether a process received the
process management break interrupt message or not. Set to true to indicate
that the process has been put into a break wait. Set to false to indicate
that the process is no longer in break wait but on the dispatcher
queue. |
| 2133 |
Break Request Cancel (I32) Put: No; Verify: Yes; Release 4.5
Returns counter used by process management to indicate whether a pending
process management break interrupt message just received is to be ignored
or not. |
| 2134 |
Break Request Pending (I32) Put: No; Verify: Yes; Release 4.5
Returns counter used by process management to indicate whether a process
management break interrupt message that is being sent has been received
and is being acted upon. The process receiving the message will be in a
break wait state. |
| 2135 |
List of sibling PIDs (REC) Put: No; Verify: No; Release 4.5
Returns a list of PIDs of all the sibling processes. The maximum size is a
system constant, obtainable from AIFSCGET. You should pass a buffer of
appropriate size. The first word of the buffer is expected to hold the
size, in longwords, of the rest of the buffer area. The first word, upon
return, specifies the number of PIDs returned. Check itemstatus_array to
see if information was truncated.
Record type: I64rec_type (Refer to appendix B) |
| 2136 |
List of parent PIDs (REC) Put: No; Verify: No; Release 4.5
Returns a list of PIDs of all the parent processes. The maximum size is a
system constant, obtainable from AIFSCGET. You should pass a buffer of
appropriate size. The first word of the buffer is expected to hold the
size, in longwords, of the rest of the buffer area. The first word, upon
return, specifies the number of PIDs returned. Check itemstatus_array to
see if information was truncated.
Record type: I64rec_type (Refer to appendix B)
|
| 2142 |
Interactive? (B) Put: Yes; Verify: Yes; Release 5.0
Returns or modifies the interactive status of the process. True when human
intervention is required for all input operations.
|
| 2143 |
Environment Nil (B) Put: No; Verify: Yes; Release 5.0
Returns whether the user has a nil environment. If a process has a nil
environment, then during startup of its child POSIX process, all the CI
variables for the job/session environment are changed into an environment
format and inherited by the child process. |
| 2144 |
Workgroup name (CA256) Put: Yes; Verify: Yes
Returns or modifies the name of the workgroup to which the specified
process belongs. The workgroup name will be left justified and terminated
by a NULL character (ASCII 0). AIFPROCPUT with this item number will move
the target process to the specified workgroup. A process moved in this
manner is considered an artificial member of the workgroup (the
process was placed in a workgroup explicitly, rather than naturally by
meeting the membership criteria specified for the workgroup). A process
remains an artificial member of its assigned workgroup until either the
workgroup is purged or its explicit assignment is changed by AIFPROCPUT
item 2146.
An artificial member is not affected by a system-wide scan or by the
changing of its process attributes used to determine workgroup membership.
If both items 2144 and 2146 are specified, then the order they are passed
will determine the outcome. If the order is item 2144 followed by item
2146, then the process will migrate to its natural workgroup. However if
item 2146 is passed followed by item 2144, then the process will be
pegged to the name of the workgroup passed as its artificial member.

Artificial Member? (B) Put: No; Verify: Yes |
Returns true if the specified process is an artificial member of its
workgroup.
| 2146 |
Return to Natural Workgroup (B) Put: Yes; Verify: No
Returns the specified process to its natural workgroup. This item will
return a warning for AIFPROCGET in the item status array. This item allows
the process to migrate to its natural workgroup. If the process is an
artificial member of a workgroup, this item will release the process from
its explicit workgroup assignment. However a process who is a member of
its natural workgroup will not be impacted.

Execution State? (I32) Put: No; Verify: Yes
Returns the execution state of the process. Values and their meanings are:
| 0 | Blocked for memory manager. |
| 1 | Unused. |
| 2 | Blocked for control block. |
| 3 | All purpose block, usually waiting for a message. |
| 4 | Ready to execute (or executing). |

Fixed Priority? (I32) Put: Yes; Verify: NO
Fixes the priority of the process at the value passed. This item will
return a warning for AIFPROCGET.
A valid MPE/iX priority is in the range 0 .. 32767. This priority can be
mapped to MPE V priority by the following formula:
(All formula values are decimal.)
MPEVPri = (32767 - MPEXLPri) DIV 128
