[comp.sys.mac.programmer] Main screen pixMap base address?

Hi,

A few weeks ago, some one posted a message about the fact that when accessing
the base address of the pixMap of the main screen device, the address is
always 0 (zero). I have run into that problem myself,
and I would like to know how to get at the base address.

I have got at the base address of other screens besides the main --
No Problem.

If some one has some wisdom to impart here ( including references to IM), I
would appreciate it.

My system is a Mac IIx with Multifindinder, sys 6.0.5. And i am using
Think C 4.0.2 for development.

Thanx,
Jennifer Lanham
