ADLINK cPCI-7252 - Manual (Page 38)

28 C/C++ Libraries
In order to recognize the difference between the DOS library and
Windows 95 library, a capital "W" is placed at the start of each
function name for Windows 95 DLL drivers. e.g.
W_7252_Initial().
Data Types
We have defined some data types in the Pci_7250.h (DOS) and
Acl_pci.h (Windows 95) header files. These data types are used
by the NuDAQ card library. We recommend you use these data
types in your application programs. The following table shows the
data type names and their range.
5.3 Running Testing Utility (7250UTIL.EXE)
After finishing the DOS installation, you can execute the utility by
typing the following command:
The following:
C> cd\ADLINK\7252\DOS\UTIL
