[Qemu-devel] Debugging with printf

[Qemu-devel] Debugging with printf

Hello. I'm working with Android Emulator (which as I understand is
something like QEMU but not the same) and I would like to print messages
concerning the Emulator. What I mean is that I want to edit the source code
of the Emulator (adding some *printf*s to it) and display the results or
write them to a file. Can someone help me, please?

Please ask the Android (Emulator) community for help.  This list is
about QEMU and we don't know specifics of the Android Emulator.

I understand that they're not one and the same but there are similarities.
After all the Emulator is based on QEMU. How would someone go about editing
QEMU source to display messages?

There are also similarities in editing any C program to display message. 
You didn't say what information you want from QEMU and you said you know 
it's about adding printf's, then what's the problem you have there? 
Please be specific about your question. If you want to know how to get 
or build the source code, here are some instructions:

My problem is how do I read the information I want to print. From where?
What do I do?
