5.2Programming Guide

5.2.1Naming 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. _9112_Initial().

All functions in PCI-9112 driver are with 9112 as {hardware_model}. But they can be used by PCI-9112, cPCI-9112.

In order to recognize the difference between DOS library and Windows 95 library, a capital "W" is put on the head of each function name of the Windows 95 DLL driver. e.g. W_9112_Initial().

5.2.2Data Types

We defined some data type in Pci_9112.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.

Type Name	Description	Range
U8	8-bit ASCII character	0 to 255
I16	16-bit signed integer	-32768 to 32767
U16	16-bit unsigned integer	0 to 65535
I32	32-bit signed integer	-2147483648 to 2147483647
U32	32-bit single-precision	0 to 4294967295
	floating-point

F32	32-bit single-precision	-3.402823E38 to 3.402823E38
	floating-point

F64	64-bit double-precision	-1.797683134862315E308 to
	floating-point	1.797683134862315E309

Boolean	Boolean logic value	TRUE, FALSE
