daqX API - Command Reference D-1

daqX API - Command Reference Appendix D

Commands in Alphabetical Order…… D-3

API Reference Tables…… D-31

This chapter describes the WaveBook driver commands for the daqX API (Windows 95/98 and

Windows NT in 32-bit Enhanced mode). 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. Lastly, 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.

Note:The daqx API provides a common Application Programming Interface for 32-bit data acquisition

applications. The WaveBook Enhanced API is a subset of daqX Enhanced API.
