6 Function Library

This chapter describes the supporting software for PCI-8124-C.

User can use these functions to develop programs in C, C++, or

Visual Basic.

6.1 List of Functions

This section details all the functions. The function prototypes and

common data types are declared in pci_8124.h and type_def.h.

We suggest you use these data types in your application pro-

grams. The following table shows the data type names and their

range.

Table 6-1: Data Type Definitions

The functions of the PCI-8124-C’s software drivers use full-names

to represent the functions real meaning. The naming convention

rules are:

In a ‘C’ programming environment:

 _{8124}_{action_name (lower case)} e.g. _8124_initial ()

In order to recognize the difference between a C library and a VB

library, a capital “B” is placed at he beginning of each function

name e.g. B_8124_initial ().
