Cisco Cisco Computer Telephony Integration Option 9.0 Developer's Guide

The CTI OS Client Interface Library is designed to be a single interface, which 
can be used across multiple languages and environments (e.g. C++, COM, Visual 
Basic, Java, and .NET). However, each programming language has its own native 
data types. Throughout this document, the interface parameters will be listed with 
the following standardized data types:

STRING: This is a variable-length string variable. If a maximum length 

exists, it is listed with the parameter description.

INT: This is a 32-bit wide integer. 

UNSIGNED INT: This is a 32-bit wide unsigned integer. 

SHORT: This is a 16-bit wide short integer. 

UNSIGNED SHORT: This is a 16-bit wide unsigned short integer. 

BOOL: This is a logical true or false variable. Different implementations will 
use different sized variables to represent this type. In COM, the 
VARIANT_BOOL is used. Tests of variables of this data type must be 
against VARIANT_TRUE and VARIANT_FALSE and not simply against 0 
or 1.

ARGUMENTS: This is a custom data structure used by CTI OS, which holds 

a variable-length set of key-value pairs.

ARG: This is an individual element (value), which can be stored in an 

ARGUMENTS structure.
