Don't know what mean "System Error XXX" where XXX is a negative number.
Please read this page before posting : Symbian OS Error Codes

You've got a Panic (a message like "KERN-EXEC 3") ? Read the Panic Reference which is in your SDK documentation

To display panics details on your device: http://www.newlc.com/Display-the-extended-panic-code-in.html

Re: System Error XXX and Panics
Well done Eric... Now this will reduce lot of queries related with Panics and System errors  Cool
But still you know some of the panic's are not yet documented in the SDK help, like EIKON-LISTBOX.

Re: System Error XXX and Panics
For tracking down a leave code, I use find in files ( because I'm lazy ) and search the epoc32\include directory for the negative number wrapped up in brackets...

(-11) for instance

Since most leave codes are defined in the epoc32\include\e32std.h file

E32STD.H(129): const TInt KErrAlreadyExists=(-11);

I also notice that Eric (or somebody) has placed a really handy guide to leave codes and panics as a tutorial on newlc! - Great - Smiley

Re: System Error XXX and Panics
Good links, even though I came across them before. But I'm still very confused about use of these things. I mean, when should I, in my code, use panics and when leave. So far I try think of it as the code should leave when I have a run-time error (memory allocation) and panic when there is a bug, eg. wrong(short) descriptor passed as a parameter and so on. Am I right? I'm not sure about the panics.

You've pretty much got it - Panics are terminal, indicating a programming error, and Leaves indicate runtime errors which you need to subsequently deal with/roll-back from.
Jo Stichbury's Symbian OS Explained (http://www.amazon.co.uk/exec/obidos/ASIN/0470021306/) has a good explanation of Leaves and Panics, which I would recommend.

Re: System Error XXX and Panics
I know Jo Stitchbury very well and her book is indeed very good, there is also a book due out by Rob Falla which covers much of the basics also. Either way they should both be able to help

Re: System Error XXX and Panics
Some types of error are due to bad program code. When this type of error is discovered, the thread associated with the erroneous program should be terminated. In Symbian OS, this is a referred to as a panic. The only proper response to a panic is to fix the program code....

Re: System Error XXX and Panics
I found this link recently from the Symbian FAQ & Tech Tips. There you can find the range of error code and the corresponding header file name. Hence it's not a latest list; the list was last updated on 4 May 2004.

Is there a definitive list of Symbian OS error codes?

Re: System Error XXX and Panics
-30180 is a code specific to a component not part of the core O/S you will have to tell us what phone it occurs on (Ie who made it) as each manufacturer will have their own Wi-Lan stack/provider.
The error also has a very short (often capitalized) string telling us where it occurred.
