this means the call togetUSB()will try to return the USB port of a null reference, which will result in aNullPointerExceptionat runtime and stop your program from running further. Imagine if your program was ru
It means you are trying to access a NULL pointer in your code. Put NULL checks in your code to find out where.Also please note that some registers are not available for access in user mode. You need to write a driver that will access them. Regards 0 Kudos Reply 04-20-2021 06...

To release the memory referenced by a pointer, the ptr_free procedure is used: Sign in to download full-size image Once you have freed the memory referenced by a pointer, the pointer becomes invalid. This means that even though the pointer itself still exists, it can no longer be dereferen...
A common (bad) practice is to return the null reference to indicate the absence of a sound card. Unfortunately, this means the call togetUSB()will try to return the USB port of a null reference, which will result in aNullPointerExceptionat runtime and stop your program from running furth...
