Hi,
I writed, a long time ago, a CE 2.11 stream interface driver. today, i use
source code and compile it with PB 5.0. My driver work fine but,

On each IOCTRL call , the driver call MapPtrToProcess. I use it to map the
input parameter. This parameter is a pointer to a structure.

I've see in the documentation that the MapPtrToProcess is deprecated. Use
MapCallerPtr function instead. But the MapCallerPtr is use to validate
parameter, not to map adress into the caller process. Do i must use
MapPrtToProcess again?

Thank you
