5.2Programming Guide

5.2.1Naming Convention

The functions of the NuDAQ PCI cards or NuIPC CompactPCI cards’ software driver are using full-names to represent the functions' real meaning. The naming convention rules are:

In DOS Environment :

_{hardware_model}_{action_name}. e.g. _7200_Initial().

All functions in PCI-7200 driver are with 7200 as {hardware_model}. But they can be used by PCI-7200, cPCI-7200.

In order to recognize the difference between DOS library and Windows 95 library, a capital "W" is put on the head of each function name of the Windows 95 DLL driver. e.g. W_7200_Initial().

5.2.2 Data Types

We defined some data type in Pci_7200.h (DOS) and Acl_pci.h (Windows 95). These data types are used by NuDAQ Cards’ library. We suggest you to use these data types in your application programs. The following table shows the data type names and their range.
