Parameters | |
- mode
16-bit unsigned integer by reference (optional) Returns the current user's access mode. In this half word,
the bits have the following meanings:
| Bits | Value/Meaning |
|---|
| 15:1 | - 0
The job/session input file and job/session list file are not
interactive. - 1
The job/session input file and job/session list file form an
interactive pair. A person responding through the input device can
establish a dialog with a program that displays information on the list
device.
| | 14:1 | - 0
The job/session input file and job/session list file are not
duplicative. - 1
The job/session input file and job/session list file form a
duplicative pair. Images on the input device are duplicated
automatically on the list device.
| | 12:2 | - 00
Not used. - 01
The user is accessing the system through a session. - 10
The user is accessing the system through a job. - 11
Not used.
| | 0:12 | Reserved for the operating system |
- capability
32-bit signed integer by reference (optional) Returns the user's file access attributes, user attributes,
and capability class attributes if the appropriate bit = 1.
The high-order half word indicates file access attributes
and user attributes; the low-order half word indicates possession
of capability-class attributes. The significance of these
bits is as follows:
| Bits | Value/Meaning |
|---|
| 0:1 | System manager (SM) | | 1:1 | Account manager (AM) | | 2:1 | Account librarian (AL) | | 3:1 | Group librarian (GL) | | 4:1 | Diagnostician (DI) | | 5:1 | System supervisor (OP) | | 6:1 | Volume set creation (CV) | | 7:1 | Volume set usage (UV) | | 8:1 | User logging (LG) | | 9:4 | Reserved for the operating system | | 13:1 | Communications system (CS) | | 14:1 | Nonshareable devices (ND) | | 15:1 | Save files (SF) | | 16:7 | Reserved for the operating system | | 23:1 | Batch access (BA) | | 24:1 | Interactive access (IA) | | 25:1 | Privileged mode (PM) | | 26:2 | Reserved for the operating system | | 28:1 | Multiple RINs (MR) | | 29:1 | Reserved for the operating system | | 30:1 | Extra data segments (DS) | | 31:1 | Process handling (PH) |
- localattr
32-bit signed integer by reference (optional) Returns the local attributes of the user, as defined by a
user with the account manager attribute.
- username
character array (optional) Returns the user's name in an 8-character array.
- groupname
character array (optional) Returns the name of the user's logon group in an 8-character array.
- acctname
character array (optional) Returns the name of the user's logon account in an 8-character array.
- homename
character array (optional) Returns the name of the user's home group in an 8-character array. If a
home group is not assigned, this array is filled with blanks.
- term
16-bit unsigned integer by reference (optional) Returns the logical device number of the job/session input device.
If this is a spooled (STREAM) batch job, then the logical
device number is the virtual device. A virtual device simulates a spooling device. Users cannot own the
actual spooling device, so the virtual device allows users access to
spooling. Each virtual device is temporarily assigned a logical
device number for the duration of the input or output spooling
process. Since the same logical device number can be reassigned
to another virtual device with different physical characteristics,
such as page length, the virtual device is not permanently configured
in the system configuration. You can also obtain the logical device
number of the virtual device with FFILEINFO.
