Current Process State

-
-
-

The current process is the process in whose address space the -current thread was executing when the fault occurred. The 15 lines starting at -line 33 of the output gives information relating to the current process. This -has some similarities with the current thread information:

-

-

PROCESS at 64038d5c VPTR=f80342a4 AccessCount=6 Owner=00000000

-

The Process at field contains a pointer to the -DProcess object representing the process.

-

The AccessCount field contains the reference count -on the process object.

-

The owner field contains a pointer to the object -that owns this DProcess object.

-
-
-

The process name

-
-

Full name test2.exe

-

The Full name field gives the name of the process. -In this example, the name of the process is test2.exe.

-

See the thread name.

-
-

Exit information

-
-

ExitInfo 3,0,

-

The ExitInfo field contains the information that -characterises the process exit. In this example, the value is 3, meaning that -this process has not exited. See also TExitType.

-
-

Process flags

-
-

Flags a0000000, Handles 6403860c, Attributes 60010000

-

The Flags field contains information about the state -of the process. The possible values in this field are defined by the -KProcess... constants in u32std.h. While the symbols -are internal to Symbian OS, the following table summarises the values and their -meaning.

-
- - - - -
-

Symbol

-

Value

-

Meaning

-

KProcessFlagSystemCritical

-

0x00000004

-

A process panic causes the entire system to -reboot.

-

KProcessFlagSystemPermanent

-

0x00000008

-

If the process exits for any reason, then this causes the -entire system to reboot.

-

KProcessFlagPriorityControl

-

0x40000000

-

If set, then other threads are allowed to change this -thread’s priority.

-

KProcessFlagJustInTime

-

0x80000000

-

If set, then just-in-time debug is enabled for this -thread.

-
-

Handles

-
-

Flags a0000000, Handles 6403860c, Attributes 60010000

-

The Handles field contains the address of a -DObjectIx object that contains the handles owned by the -process.

-
-

Attributes

-
-

Flags a0000000, Handles 6403860c, Attributes 60010000

-

The Attributes field contains the attributes of the -process. Some are generic, as defined by -DProcess::TProcessAttributes, but others depend on the -memory model.

-
-

Information about memory

-
-
-

DataBssChunk 64039234, CodeSeg 6403919c

-

The DataBssChunk field contains a pointer to the -DChunk object representing the chunk that contains the process -data and .bss memory. Be aware that this is not the same as the -heap - heaps are allocated to threads, and chunk information is found in the -DThread object.

-

The CodeSeg field contains a pointer to the -DCodeSeg object that represents the code segment.

-
-

Secure id

-
-

DllLock 64039044, Process Lock 64038eec SID 00000000

-

The SID field contains the secure id of the -process.

-
-

Capability

-
-

TempCodeSeg 00000000 CodeSeg 6403919c Capability 00000000 0003ffff

-

The second four bytes of the Capability field contains the set of -bits that define the capability for this process. This defines what the process -can and cannot do.

-
-

Code segments

-
-

CodeSegs: Count=0

-

The CodeSegs: Count field contains the number of -code segments that have been dynamically loaded into the process. This will be -zero if the process is XIP.

-
-

Chunks owned by the process

-
-

NumChunks=2
0: Chunk 64039234, run 00400000, access count 1
1: Chunk 6403613c, run 00600000, access count 1

-

The NumChunks field contains the number of chunks owned by the -process.

-

Successive lines contain information about each chunk:

- -
-

Shared IO buffer information

-
-
-

Process shared IO buffers cookie 0000031d
Process has no shared IO buffers

-

This is information about shared IO buffers. The cookie is only -really of interest to base engineers.

-
-
-

Domain information

-
-

Domain -1, DACR 55555507

-

This is ARM MMU-specific protection information. Processes have -domain -1 and DACR 0xFFFFFFFF.
