z/TPF C/C++ APIs

The following contains an alphabetic listing of the z/TPF general services, which consists of C/C++ functions and macros. C/C++ APIs are used by z/TPF applications that need system services. No special authorization is required by the C/C++ APIs, although some parameters may be restricted, as noted.

The following information is shown for each z/TPF C/C++ API:

Purpose: Describes how and why you use the API.

Last updated: Provides historical information about when the API was added, changed, obsoleted, or replaced.

Format: The API prototype and a description of any parameters.

Normal return: Lists what is returned when the requested service has been performed.

Error Return: Lists what is returned when the requested service could not be performed. Specifying incorrect API parameters results in a system error and exits.

Programming Considerations: Lists any additional considerations for using the API, including any restrictions or limitations.

Example: Provides one or more examples that show you how to code the API.

Note: The TPF/APPC basic conversion functions and mapped conversion functions document return codes instead of the normal and error returns that are documented for all other z/TPF APIs.
