dynamic-link library (DLL)
dynamic-link library (DLL). A collection of procedures whose code and data can be loaded
and executed at any virtual memory address, with run-time resolution of links to and
from the main program and other independent libraries. The same DLL can be used by
more than one process. Each process gets its own copy of DLL static data. Compare
to shared run-time library (SRL).
EDIT file. In the Guardian file system, an unstructured file with file code 101. An EDIT file
can be processed by either the EDIT or PS Text Edit (TEDIT) editor. An EDIT file
typically contains source program or script code, documentation, or program output.
HP NonStop™ Open System Services (OSS) functions can open an EDIT file only for
reading.
file. An object to which data can be written or from which data can be read. A file has
attributes such as access permissions and a file type. In the HP NonStop™ Open
System Services (OSS) environment, file types include regular file, character special
file, block special file, FIFO, and directory. In the Guardian environment, file types
include disk files, processes, and subdevices.
file name. A string of characters that uniquely identifies a file.
In the PC environment, file names for disk files normally have at least two parts: the
disk name and the file name (for example, B:MYFILE).
In the Guardian environment, disk file names include an Expand node name, volume
name, subvolume name, and file identifier (or example,
\NODE.$DISK.SUBVOL.MYFILE).
In the HP NonStop™ Open System Services (OSS) environment, a file is identified by
a pathname (for example, /usr/john/workfile). See also filename.
filename. In the HP NonStop™ Open System Services (OSS) environment, a component of
a pathname containing any valid characters other than slash (/) or null. See also file
name.
flag. In a UNIX or HP NonStop™ Open System Services (OSS) command, a character
sequence that begins with a hyphen and is processed as a unit.
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. Compare
to option.
Guardian environment. The Guardian application program interface (API), tools, and
utilities.
