1.5.2 Programming with Device Drivers Function Library

Advantech Device Drivers offer a rich function library that can be utilized

in various application programs. This function library consists of numer-

ous APIs that support many development tools, such as Visual C++,

Visual Basic, Delphi and C++ Builder.

1.5.3 Troubleshooting Device Drivers Error

Driver functions will return a status code when they are called to perform

a certain task for the application. When a function returns a code that is

not zero, it means the function has failed to perform its designated func-

tion. To troubleshoot the Device Drivers error, you can pass the error

code to DRV_GetErrorMessage function to return the error message.

Alternatively, you can refer to the Device Drivers Error Codes Appendix

in the Device Drivers Manual for a detailed listing of Error Codes, Error

IDs and the Error Messages.
