C Run-Time Library

The C run-time library contains the functions defined in the ISO/ANSI C standard as

well as several functions that are extensions to the standard. Macros that are not in the

library are expanded during the preprocessing phase of the compiler.

The Guardian C run-time library and the OSS C run-time library share the same set of

header files. Header files contain function prototypes and the variable and type

declarations used by the functions.

For the complete semantics and syntax of the C run-time library in the Guardian TNS C

environment, see the Guardian TNS C Library Calls Reference Manual. Use of TNS C

in the G-series OSS environment was discouraged after the D40 RVU and the OSS

TNS library calls are no longer completely documented. TNS C is not available in the

H-series OSS environment.

Binder

The Binder collects and links object files generated by the TNS C compiler and

produces an executable TNS object file (a program file).

Accelerator

The Accelerator enables you to run and increase the performance of programs on

TNS/R systems. The Accelerator optimizes TNS program files (compiled and bound

object files) to take advantage of the TNS/R architecture.

Object Code Accelerator (OCA)

The Object Code Accelerator (OCA) enables you to run and increase the performance

of programs that run on TNS/E systems. The OCA optimizes TNS program files

(compiled and bound object files) to take advantage of the TNS/E architecture.

Inspect Symbolic Debugger

The Inspect symbolic debugger is an interactive tool that enables you to identify and

correct programming errors in programs.You can use the Inspect debugger to:

•

Step through code

•

Set breakpoints

•

Display source

•

Display variables

For details on TNS program debugging capabilities, refer to the Inspect Manual and

the G-series Debug Manual.
