Kernel objects such as DProcess, DThread, +DSemaphore, DChunk are all instances of classes +derived from DObject.
+To show basic information about a DObject, use +the o +command.
+To show more detail, use the +q command.
+As an example, use these commands to show information about a +DProcess object whose address is shown using the +i command:
+...
+ TheCurrentDataSectionProcess=6403bb4c
+ ...
> o 6403bb4c
+This gives:
+.o 6403bb4c
PROCESS at 6403bb4c VPTR=f8046c78 AccessCount=6 Owner=00000000
Full name crash
All objects derived from DBase have a virtual +table pointer, access count, owner and name. Using the +q command on this +address would you give you the full process information.
+You can use o to examine other +types of objects, for example chunks. The thread information for the current +data section process shows two chunks:
+NumChunks=2
0: Chunk 6403c044, run 00400000, access count 1
1: Chunk 64039688, run 00600000, access count 1
Using the o command on the first +of these chunk objects gives you the basic information:
+.o 6403c044
CHUNK at 6403c044 VPTR=f8046b50 AccessCount=1 Owner=6403bb4c
Full name crash::$DAT
Using the q command gives you +more detailed information:
+.q 6403c044

The information displayed is memory model dependent. It is +shown here for the moving memory model.
+Notes:
+Size 2000, MaxSize 200000, Base 00400000
+The Size field shows the current size of the +chunk, in bytes.
+The MaxSize field shows the maximum size of the +chunk, in bytes.
+The Base field shows the base address in the run +region.
+Attrib 6, StartPos 0
+The Attrib field shows the attributes of the +chunk.
+The StartPos field shows the offset, in bytes, +between the base address and the start of the committed area. This is non-zero +for double-ended chunks only.
+Type 6, State 2, Home Base 68900000
+The Type field shows the type of chunk. This +corresponds to a TChunkType enum value.
+The State field shows the current state of the +chunk. This corresponds to a TChunkState enum value, which is +itself defined within the scope of the Symbian OS internal class +DMemModelChunk.
+The Home Base field is the base address of the +chunk in the home region.
+Home Region Offset 00000000
Home Region Base 68900000
Home Region Size 00100000
These three lines show the offset, base address and size (the +reserved size) of the chunk in the home region.
