Naming Convention
The functions of the NuDAQ PCI cards or NuIPC CompactPCI
cards’ software driver are using full-names to represent the func-
tions' real meaning. The naming convention rules are:
In DOS Environment:
_{hardware_model}_{action_name}. e.g. _7300_Initial().
All functions in PCI-7300A driver are with 7300 as
{hardware_model}. But they can be used by PCI-7300A, cPCI-
7300.
In order to recognize the difference between DOS library and Win-
dows 95 library, a capital "W" is put on the head of each function
name of the Windows 95 DLL driver. e.g. W_7300_Initial().
Data Types
We defined some data type in Pci_7300.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.
