Naming 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. _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 Windows 95
library, a capital "
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.
