daqCommand Reference (Enhanced API) 11

TempBook User’s Manual daqCommand Reference (

Enhanced

API) 11-1

Overview

The first part of this chapter describes the TempBook driver commands for Windows95 and WindowsNT in

32-bit Enhanced mode (this is the Enhanced API and is not to be confused with the Standard API). The

first table lists the commands by their function types as defined in the driver header files. Then, the

prototype commands are described in alphabetical order as indexed below. Note: The TempBook API is a

subset of the Daq* API which also applies to other products; only TempBook-related commands are

described here.

Beginning on page 11-35, several reference tables define parameters for: event-handling definitions,

hardware definitions, ADC trigger-source and miscellaneous definitions, WBK card definitions, the API

error codes, etc.
