Debug Monitor

## c - Display Contents of Object Container

This command displays the contents of one of the kernel's object containers, a DObjectCon type. Note that information is dumped very quickly without page breaks, which is useful in situations where the kernel is likely to become very unstable very shortly after crashing. There is an upper case version of this command, C, which generates output with a pause between pages.

The command has the following syntax:

c type

where type is a single hexadecimal digit between 0 and D inclusive that specifies which kernel container is to be dumped. The mapping between the hexadecimal digit and the kernel container is:

0 | Threads
1 | Processes
2 | Chunks
3 | Libraries
4 | Semaphores
5 | Mutexes
6 | Timers
7 | Servers
8 | Sessions
9 | LogicalDevices
A | PhysicalDevices
B | Channels
C | ChangeNotifiers
D | Undertakers
E | Message queues
F | Property references

For example:

> c A

The information displayed for each object is the same as that shown after using the q command. After displaying the information for each object, the debugger pauses until you press a key.

Notes

- the DObjectCon class is internal to Symbian OS.

- the type value passed as an argument to the command is one of the enum values of the TObjectType enum; this enum is internal to Symbian OS.
