Library Functions

The Developer's Toolkit for OS/2 Warp Version 4 libraries are divided into two parts:

• Standard libraries, which define the SAA features and The Developer's Toolkit standard extensions to SAA

• Subsystem libraries, which are a subset of the standard libraries, and are used for subsystem development. The functions in these libraries do not require a run-time environment.

This section lists alphabetically and describes all the functions that The Developer's Toolkit for OS/2 Warp Version 4 product offers, including the extensions to the ANSI/ISO C definition. For information on the subsystem libraries and the functions in them, see the chapter called "Developing Subsystems" in the VisualAge C++ Programming Guide.

Each function description includes the following subsections:

Syntax

The prototyped declaration of the function and the header file in which it is found. To include the declaration in your code, include the header file.

A brief description of what the function does, what parameters it takes, and how to use the function.

The value returned from a successful call to the function and the error return value.

A short example of how to use the function. From the online C Library Reference, you can use the IPF Copy to File choice from the Services pull-down to copy a function example to a separate file (called TEXT.TMP by default). You can then compile, link, and run the example, or use the example code in your own source files.

A list of other functions that are similar to or related to the function, and of other topics that provide additional information that help you use the function.
