8.1 Introduction

This chapter provides a comprehensive, alphabetically-ordered reference to the NCC service functions. A prototype of each function is shown with the function description and details of all arguments and return values. A typical function description includes:

Prototype

The prototype is shown followed by a listing of the function's arguments. Natural MicroSystems data types include:

· WORD 16 bit unsigned

· DWORD 32-bit unsigned

· INT16 16-bit signed

· INT32 32-bit signed

· BYTE 8-bit unsigned

If a function argument is a data structure, the complete data structure is defined.

Return Values

The return value for a function is either SUCCESS or an error code. For asynchronous functions, a return value of SUCCESS indicates the function was initiated; subsequent events indicate the status of the operation.

Refer to Appendix B for a listing of all errors returned by NCC service functions.

Events

If events are listed, the function is asynchronous and is complete when the DONE event is returned. If there are no events listed, the function is synchronous.

Additional information such as reason codes and return values may be provided in the value field of the event.

Refer to Chapter 9 for details for all NCC service events and reason codes.
