hi, all:
i want to add a function in xen. in the function i need to call the
"printk" to display the values of some variables.
i found the definition of printk() in file
"xen-3.1.0-src\xen\include\xen\lib.h ":
extern void printk(const char *format, ...)
__attribute__ ((format (printf, 1, 2)));
who can tell me the location of printk()?
thanks in advance.

thanks for a reply.
in my opinion, the "printk" is not what i want. the reason is:
firstly, in 'drivers/char/console.c' there is a definition of printk,
but the file includes a header file - 'xen/lib.h'.
in 'xen/lib.h' there is a declaration of printk in form of "extern
void printk()", so i doubt that the two functions is not the same one.
secondly, in 'xen/include/xen/console.h' there is not a declaration of
printk, but why the decalaration of printk() is placed into the
"xen/lib.h" file, meanwhile it is added a perfix 'extern' ?
so, can we talk about that? give me you advices please.

Hi,
I think 'printk' you meant is implemented in
'drivers/char/console.c'.
Is my answer what you want?

thanks for you.
now, by studying the printk.c of linux, i confirm that the two functions is the
same.

I'm sorry I'don't know exactly..
However, It seems that the declaration(include/xen/lib.h) and the
definition(driver/char/console.c) is the same.
