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. _6308_Initial().
All functions in PCI-6308 driver are with 6308 as {hardware_model}. But
they can be used by PCI-6308V, PCI-6308A.
In order to recognize the difference between DOS library and Windows
95 library, a capital "
Windows 95 DLL driver. e.g. W_6308_Initial() .

Data Types
We defined some data type in Pci_6308.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.
