Weird Behaviour in Printf

[LAS__VEGAS]

Hello,
I have 2 questions. I had this line in my code:

// Globals
TInt		iBytes = 0;
TInt		iFiles = 0;
TInt		iFolders = 0;
...
void function f()
{
...
console->Printf(_L("%f bytes (%d folders and %d files) copied\n"), iBytes, iFolders, iFiles);
...
}

In the debugger at this line, all 3 variables have some non-zero values let's say X,Y,Z.
This code prints :
"0.0000 bytes (Y folders and 0 files) copied".

But when I change the line to

console->Printf(_L("%d bytes (%d folders and %d files) copied\n"), iBytes, iFolders, iFiles);

(i.e. change %f to %d)This code prints:
"X bytes (Y folders and Z files) copied"

So I am curious about this behaviour in the first code. Why it is so(i.e iBytes does not work that's ok,but why iFolders works and not iFiles)?

And second question, how can I see the implementation of the Printf(i.e. where is e32cons.cpp)? VC++ 6 shows only e32cons.h file.

Thanks in advance for your responses.

OK, I figured out answer of my first question.

TReal is 8 bytes, TInt is 4 bytes. So printf first tries to insert a float and fetches 8 bytes(i.e. tries to print X + Y) and it is not a valid float so it prints 0. Then it fetches next 4 bytes(range 9-12 where Z is located) , to insert Y. Then it fetches Z (range 13-16 , it is garbage) and prints 0.

The bad luck here is that in my test case Y was equal to Z. So I thought it prints Y correctly and not Z. where in reality it was printing Z as Y.

My 2nd question is still valid though, can I see the source code of Symbian SDK?

You will need to purchase the DevKit from Symbian for the Source Code for Symbian

By the way I don't know what devices you are targetting but generally writeable static data data like you have is not supported when build for ARM processors on Symbian. The exception being a .exe (console app)
