Hi All,
I build a 64-bit kext in snow leopard. It communicate with the client application with memory mapping.
It seems that it is impossible to map address in 32-bit application to 64-bit kext.
Do you guys know how to handle this?
In Leopard 10.5, I face a similar problem between 64-bit application and 32-bit kext.
Apple has an API withAddressRange() with 63-bit address can handle that problem.
But it seems that it cannot handle the problem between 32-bit application and 64-bit kext.
Who knows the solution?
Thanks!
