108 Function Library
6.2 C/C++ Programming Library
This section details all the functions. The function prototypes and
some common data types are declared in
pci_8174.h . We sug-
gest you use these data types in your application programs. The
following table shows the data type names and their range.
Table 6-1: Data type definitions
The functions of the PCI-8174 software drivers use full-names to
represent the functions real meaning. The naming convention
rules are:
In a ‘C’ programming environment:
_{hardware_model}_{action_name}. e.g.
_8174_initial()
.
In order to recognize the difference between a C library and a VB
library, a capital “B” is placed at the beginning of each function
name e.g.
B_8174_initial()
.
