4.1 Introduction

This chapter provides a comprehensive, alphabetically-ordered reference to the ISUP data API functions. A prototype of each function is shown with the function description, details of all arguments, and return values. Some of the fields in the function definition include:

Prototype

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

 · DWORD

· S16

· U32

· Bool

 8-bit unsigned
16-bit signed
32-bit unsigned
8-bit unsigned

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

Note: Not all parameters are applicable to both ANSI and ITU-T (CCITT) networks.

Return Values

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