public dynamic-link library (public DLL)
public dynamic-link library (public DLL). Optional native-mode executable code modules
available to all native user processes. A public library that is specified in the public
library registry, supplied by HP or, optionally, a user. Contrast with ordinary
dynamic-link library (ordinary DLL).
public library. A dynamic-link library (DLL) or shared run-time library (SRL) that is known to
the operating system, available for execution by any process or user, and is not an
implicit library.
public shared run-time library (public SRL). A TNS/R library supplied by HP.
PVC. See permanent virtual circuit (PVC).
QoS. See Quality of Service (QoS).
Quality of Service (QoS). Quality of Service is defined on an end-to-end basis in terms of
the following attributes of the end-to-end ATM connection: cell loss ratio, cell transfer
delay, and cell delay variation.
request for comment (RFC). The development of TCP/IP standards, procedures and
specifications is done via this mechanism. RFCs are documents that progress through
several development stages, under the control of Internet Engineering Task Force
(IETF), until they are finalized or discarded.
re-exported library. A library whose symbols are made available by another dynamic-link
library (DLL) to any localized client of that DLL. Re-export is an attribute of the DLL’s
libList entry for that library. This attribute is specified by the DLL’s programmer and
recorded by the linker as a DLL is built. It affects only localized clients of the DLL. This
feature allows a symbol to be moved from one DLL to another without relinking clients
of the original DLL.
Re-exporting is transitive; that is, if A re-exports B and B re-exports C, then A re-
exports C. Re-exported libraries can re-export other libraries to form a succession of
re-exported-libraries of arbitrary length.
release version update (RVU). A collection of compatible revisions of Nonstop Kernel
operating system software products, identified by an RVU ID, and shipped and
supported as a unit. An RVU consists of the object modules, supporting files, and
documentation for the product revisions. An RVU also includes a set of documentation
for the overall RVU.
RFC. See request for comment (RFC).
rld library. A library that loads position-independent code (PIC) programs and their
associated dynamic-link libraries (DLLs). The rld library also provides the dlopen(),
dlclose(), dlresultcode(), dlsys(), and dlerror() functions.
router. See ServerNet router
