file type
In some UNIX and NFS implementations, the term file system means the same thing
as fileset. That is, a file system is a logical grouping of files that, except for the root of
the file system, can be contained only by directories within the file system. See also file
system.
file type. A designation for a file structure. See entry-sequenced file, key-sequenced file.
relative file, and unstructured file.
flat segment. A type of logical segment. Each flat segment has its own distinct address
range within the process address space that never overlaps the range of any other
allocated segments. Thus all allocated flat segments for a process are always available
for use concurrently. See also logical segment and selectable segment.
fully qualified file name. The complete name of a file, including the node name. For
permanent disk files, this consists of a node name, volume name, subvolume name,
and file ID. For temporary disk files, consists of a node name, subvolume name and a
temporary file ID. For a device, it consists of a node name and a device name or
logical device number. For a named process, it consists of a node name, and a
process name. For an unnamed process it consists of a node name, CPU number,
PIN, and sequence number. Contrast with partially qualified file name.
graphical user interface (GUI). A user interface that offers point-and-click access to
program functions.
group list. An Open System Services (OSS) process attribute that is used with the effective
group ID of the process to determine the file access permissions for the process.
Guardian. An environment available for interactive or programmatic use with the HP
NonStop™ operating system. Processes that run in the Guardian environment usually
use the Guardian system procedure calls as their application program interface.
Interactive users of the Guardian environment usually use the HP Tandem Advanced
Command Language (TACL) or another HP product’s command interpreter. Contrast
with Open System Services (OSS).
Guardian environment. The Guardian application program interface (API), tools, and
utilities.
Guardian services. An application program interface (API) to the HP NonStop™ operating
system, plus the tools and utilities associated with that API. This term is synonymous
with Guardian environment. See also Guardian.
Guardian user ID. See HP NonStop™ operating system user ID.
GUI. See graphical user interface (GUI).
header. An object that, when specified for inclusion in a program’s source code, causes the
program to behave as if the statement including the header were actually a specific set
of other programming statements. A header contains coded information that provides
details (such as data item length) about the data that the header precedes.
