Can anyone help me to find a good source that explains how the printf function works internally?

Thanks in advance!

This here will provide you with a start, but you'll have to dig deeper from there: The Anatomy of an Old Friend: printf[^]

Hope this helps some! If your really want to get to grips with this stuff though you'll have to grab yourself some open source C compiler with the complete source code for the standard libraries. Then you can analyze how the functions of the standard libraries are implemented.

Best Regards,
Manfred

5+ Nice link, friendly article - I've installed Visual Studio 2010 in "C:\Vs10" so the implementation of the printf formatting functionality can be found in C:\Vs10\VC\crt\src\output.c

Good call, Espen! I didn't even know that (some?) of the standard lib stuff was available as source code in VS.

Nice isn't it? another source of learning material we sometimes find useful. Here is another nice link: http://referencesource.microsoft.com/netframework.aspx

I would vote for this if I could.
Thank you, Espen.
