Hi,

I am new to JNIWrapper and am trying to invoke a method on a DLL (lets assume DLLA for this example) and the method signature looks like below

ULONG GetDevice ( DWORD dwDeviceContext, char *pcDevName );

brief description of the parmeters

dwDeviceContext - This is the device number of the device. This must be set to 1 to get the first device in the system. Increment it by 1 to get the next device name.

pcDevName - Pointer to the buffer where the device name will be stored.

I am not sure how to map the JNIWrapper call to this function. Below is how my code looks. I do not get any data back from the DLL call. I know the DLL works since i have tried the same thing with other DLL Wrappers. This is my first time with thei application so it si certainly something i am doing. I would appreciate any help in getting this working or getting a better understanding of how this works.

com.jniwrapper.Pointer deviceNameContext =

new com.jniwrapper.Pointer(deviceNameANSI);

int deviceCounter = 1;

Int deviceNumber =

new Int(deviceCounter);

returnValue = callingFunction.invoke(null, new com.jniwrapper.Pointer(deviceNumber), deviceNameContext);

System.out.println(

"device name "+ deviceNameANSI);

Thanks,

Nitin
