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 conventions are:
_{hardware_model}_{action_name}. e.g.
_7260_Initial().
All functions in the PCI-7260 drivers are with 7260 as
{hardware_model}.
Data Types
We have defined some data types in Pci_7260.h. These data
types are used by NuDAQ Cards’ library. We suggest you use
these data types in your application programs. The following table
shows the data type names and their range.
