TNS/R native mode
TNS/R native mode. The primary execution environment on a TNS/R system, in which
native-compiled MIPS object code executes, following TNS/R native-mode compiler
conventions for data locations, addressing, stack frames, registers, and call linkage.
Compare to TNS interpreted mode and TNS accelerated mode. See also TNS/E native
mode.
TNS/R native object code. The MIPS RISC instructions that result from processing
program source code with a TNS/R native compiler. TNS/R native object code
executes only on TNS/R systems, not on TNS systems or TNS/E systems.
TNS/R native object file. An object file created by a TNS/R native compiler that contains
MIPS RISC instructions and other information needed to construct the code spaces
and the initial data for a TNS/R native process.
TNS/R native process. A process initiated by executing a TNS/R native object file.
Compare to TNS process and TNS/E native process.
TNS/R native shared run-time library (TNS/R native SRL). A shared run-time library
(SRL) available to TNS/R native processes in both the Guardian and Open System
Services (OSS) environments. TNS/R native SRLs can be either public or private. A
TNS/R native process can have multiple public SRLs but only one private SRL.
TNS/R native user library. A user library available to TNS/R native processes in both the
Guardian and Open System Services (OSS) environments. A TNS/R native user library
is implemented as a special private TNS/R native shared run-time library (TNS/R
native SRL).
top margin. An empty area of a logical page that precedes the page body.
trap. A software interrupt that provides a way of handling certain events, such as detection
of a hardware (or software) fault, a timer expiration, or a lack of system resources. A
trap is often an indication of a run-time event that requires immediate attention. Most
such events preclude continuing the interrupted instruction stream. Traps are
generated for TNS Guardian processes. (native Guardian processes and all OSS
processes receive signals instead.) An Instruction Failure trap indicates that an
instruction cannot executed because the instruction or its data are invalid. Compare to
signal.
truth value. The result of evaluating a condition to determine one of two values: TRUE or
FALSE.
unary operator. A plus sign (+) or minus sign (-) that precedes a variable or a left
parenthesis (but does not follow a variable, numeric literal, or right parenthesis) in an
arithmetic expression and that has the effect of multiplying the expression by +1 or -1,
respectively.
