ADLINK PCI-8124-C - Manual (Page 67)

Function Library 57
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 ().
