Global and Static Variable initialisation Problem on MAC-OSX 10.3.3 & GCC 3.3 ........
by Gaurav Kumar 06 Feb '06

06 Feb '06

site_archiver(a)lists.apple.com Delivered-To: Darwin-dev(a)lists.apple.com Organization: hi all I am using GCC 3.3 for compiling my process on MAC-OS X 10.3.3. I am constructing a global static variable i.e object of a class in another class file. I have included that class header. The error is Abort Trap after the object construction. Anywhere in my project if i make global object of that class, the execution don't go beyond that. That class object depends upon some other global variables. If we explicitly initialize those variables then also it throws error. The global variable calls its constructor properly. But the pointer of the global variable works when we initialize it in main i.e Local pointer. Can you suggest what is real problem in initializing global variable or the in which i should proceed to solve the bug. if you require any more information do mail me.

Walking up the device segments getting the base of each with DKIOCGETBASE seems like it will work. I don't think it will. Most of Apple's partition schemes (all?) hide free space by not creating IOMedia objects for them. I don't think your method will be able to account for this. You could catch it by comparing a calculated sum of all the IOMedia object with the size of the whole disk, but I that won't help you get around the problem. And yes, free space between partitions is pretty common in the wild. I seem to recall that DiskUtility did it for awhile (and may still) but I could be wrong about that. The point is that nothing in the way a PartitionScheme driver works requires that it expose the entire drive, nor that the exposed sections be contiguous, or in any particular order. -- ______________________________________________________ Arguing with an engineer is like wrestling with a pig in mud.

Are you doing raw access to the whole disk? or to a slice (partition) of that disk? The offset may already be dealt with for you depending on how you are doing your IO. -Shawn _______________________________________________ Do not post admin requests to the list.
