conversion error

NTDEV
1

I have a conversion error when I call
InterlockedCompareExchange((PVIOD*) pIRP, IRP, NULL).

It states:

device.cpp(570) : error C2664: ‘InterlockedCompareExchange’ : cannot
convert parameter 1 from ‘PVOID *’ to ‘volatile LONG *’

I have tried to use (PLONG), but it doesn’t work.

I am compiling under Windows XP x86 Checked Build Environment.

Does any one knows how to solve this?

Use InterlockedCompareExchangePointer.
