Programming with DLL Driver Function Library

Advantech DLL driver offers a rich function library to be utilized in vari-

ous application programs. This function library consists of numerous

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

Basic, Delphi and C++ Builder.

According to their specific functions or services, those APIs can be cate-

gorized into several function groups:

❏ Digital Input/Output Function Group

❏ Counter Function Group

❏ Port Function Group (direct I/O)

❏ Event Function Group

For the usage and parameters of each function, please refer to the Func-

tion Overview chapter in the DLL Drivers Manual.

Troubleshooting DLL Driver 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 DLL driver error, you can pass the error code to

DRV_GetErrorMessage function to return the error message. Or you

can refer to the DLL Driver Error Codes Appendix in the DLL Drivers

Manual for a detailed listing of the Error Code, Error ID and the Error

Message.
