5.2Programming Guide

5.2.1Naming 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 Windows 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()).

5.2.2 Data Types

Some data types are definded 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.

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
