Naming Convention
The functions of the NuDAQ PCI cards or NuIPC CompactPCI
cards’ software drivers use full-names to represent the functions'
real meaning. The naming convention rules are:
In DOS:
_{hardware_model}_{action_name}. e.g. _7200_Initial().
All functions in the PCI-7200 driver are named with 7200 as
{hardware_model}. But they can be used by PCI-7200, cPCI-7200
and LPCI-7200S.
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_7200_Initial()).
Data Types
Some data types are defined in Pci_7200.h (DOS) and Acl_pci.h
(Windows 95). These data types are used by NuDAQ Cards’
library. We suggest using these data types. The following table
shows the data type names and their range.
