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.
