linkfile
compilation units’ linkfiles to create an executable loadfile for a native program or
library.
linkfile. (1) For native C/C++ compilers in the Guardian environment, a command file for
input to the nld or ld utility. (2) A file containing object code that is not yet ready to
load and execute. Linkfiles are combined by means of a linker or binder to make an
executable loadfile for a program or library. Compiling creates one linkfile per
independent source module. Contrast with loadfile.
linking. The operation of collecting, connecting, and relocating code and data blocks from
one or more separately compiled object files to produce a target object file.
link name. In the Open System Services (OSS) environment, the filename associated with
a specific file within a directory. The length of a filename, and therefore the length of a
link name, depends on the file system.
Linux. Linus Torvald’s version of the UNIX operating system. See also
http://www.linux.org.
listener. The process or server that is notified by the message system that a message from
some other process or server is being delivered.
LIU. See line interface unit (LIU).
LMU. See logical memory unit (LMU).
load. (1) To transfer the HP NonStop™ Kernel operating system image or a program from
disk into a computer’s memory so that the operating system or program can run. (2) To
insert a tape into a tape drive, which prepares it for a tape operation (read or write).
loadable library. A loadfile that offers functions and data to other loadfiles. In this manual,
dynamic-link libraries and hybrid shared run-time libraries are libraries. A library cannot
normally be invoked externally; for example, by a RUN command. Instead, it is
invoked by calls or data references from client loadfiles.
loader. A programming utility that transfers a program into memory so it can run. The
mechanism that brings loadfiles into memory for execution, maps them into virtual
address space, and resolves symbol references among them. Synonyms include
run-time loader and run-time linker. The loader for TNS and for TNS/R native programs
and libraries that are not position-independent code (PIC) is part of the operating
system. For PIC loadfiles, a loader called RLD works with the operating system to load
programs and libraries.
loadfile. An executable object code file that is ready for loading into memory and executing
on the computer. Loadfiles are further classified as executable programs (containing a
main routine at which to begin execution of that program) or executable libraries
(supplying routines or variables to multiple programs or separately loaded libraries). A
TNS code file might be both a loadfile and a linkfile; native code files are never both.
Contrast with linkfile.
