Programming with Device Drivers Function Library
Advantech Device Drivers offers a rich function library to be utilized in various appli-
cation 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 categorized into
several function groups:
Digital Input/Output Function Group
Port Function Group (direct I/O)
Event Function Group
For the usage and parameters of each function, please refer to the Function Over-
view chapter in the Device Drivers Manual.
Troubleshooting Device 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 function. To troubleshoot the Device
Drivers error, you can pass the error code to DRV_GetErrorMessage function to
return the error message. Or you can refer to the Device Drivers Error Codes Appen-
dix in the Device Drivers Manual for a detailed listing of the Error Code, Error ID and
the Error Message.
