Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.

In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

International Standard ISO/IEC 13719-2 was prepared by ECMA (as Standard ECMA-158) and was adopted, under a special"fast-track procedure", by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC.

This second edition cancels and replaces the first edition (ISO/IEC 13719-2:1995), which has been technically revised.

ISO/IEC 13719 consists of the following parts, under the general title Information technology - Portable Common Tool Environment (PCTE):

• Part 1: Abstract specification
• Part 2: C programming language binding
• Part 3: Ada programming language binding
• Part 4: IDL binding (Interface Definition Language)

Annex A forms an integral part of this part of ISO/IEC 13719.

1 Scope

This part of ISO/IEC 13719 defines the binding of the Portable Common Tool Environment (PCTE), as specified in ISO/IEC 13719-1, to the C programming language.

A number of features are not completely defined in ISO/IEC 13719-1, some freedom being allowed to the implementor. Some of these features are specified as implementation limits. Some constraints are placed on these implementation limits by this part of ISO/IEC 13719. These constraints are specified in clause 24, Implementation Limits.

PCTE is an interface to a set of facilities that forms the basis for constructing environments supporting systems engineering projects. These facilities are designed particularly to provide an infrastructure for programs which may be part of such environments. Such programs, which are used as aids to system development, are often referred to as tools.
