Abstract for DWARF/ELF Extensions Library Reference
This information supports IBM® z/OS® (5650-ZOS) and contains information about z/OS Runtime Library Extensions.
- Purpose of this information
- This information is the reference for IBM extensions to the
libdwarf
andlibelf
libraries.Note: This document discusses only IBM extensions and does not provide a detailed explanation of standard DWARF and ELF APIs. - Who should read this information
This information is intended for programmers who will be developing program analysis applications and debugging applications for the on the z/OS operating system. The libraries provided by CDA allow applications to create DWARF debugging information in ELF object file format. They also allow applications to query DWARF debugging information from ELF object files or GOFF program object files on the z/OS operating system.
- How to use this information
- It is assumed that you have a working knowledge of the following items:
- The z/OS operating system
- The
libdwarf
APIs - The
libelf
APIs - The ELF ABI
- Writing debugging programs in C, C++ or COBOL on z/OS
- The IBM z/OS Language Environment®
- POSIX on z/OS
- z/OS UNIX System Services shell
- Terminology used in this information
- This document uses the following terminology:
- API
- Application programming interface. An interface that allows
an application program that is written in a high-level language to
use specific data or functions of the operating system or another
program. An extension to a standard DWARF API can include:
- Extensions to standard DWARF files, objects, or operations
- Additional objects or operations
- object
- In object-oriented design or programming, a concrete realization (instance) of a class that consists of data and the operations associated with that data. An object contains the instance data that is defined by the class, but the class owns the operations that are associated with the data. Objects described in this document are generally a type definition or data structure, a container for a callback function prototype, or items that have been added to a DWARF file.
- operation
- In object-oriented design or programming, a service that can be requested at the boundary of an object. Operations can modify an object or disclose information about an object.
