Is there any way to share memory between user and kernel in the Windows 98?

If shared memory can be used then how? (in 98)

 

Thanks in advanced,

In Win98 The memory between 2GB to 3GB address range is shared between
all processes. I believe you have a VxD and if so you can use
_PageReserve call to reserve a page in shared memory and _PageCommit to
commit the page. After this pass the address to the application and have
fun.

Hope this helps,

-Srin.
