Windows CE 3.0: Application Programming (Prentice Hall Series on Microsoft Technologies)

Errors can occur either in the way the RAPI function is called on the desktop, or on the execution of the function on the Windows CE device. If a RAPI function call fails, the function CeRapiGetError returns an error from the device, or 0 if the error was a Win32 error. GetLastError can be called to determine the actual desktop error in this case. The following code shows error handling for a failed RAPI function.

int nErr = CeRapiGetError(); if(nErr == 0) cout "RAPI function failed, Win32 Error" GetLastError() endl; else cout " RAPI function failed, RAPI Error" nErr endl;
