Tags browsers generally do not work with the glibc sources due to heavy
use of the preprocessor, unfortunately.

stdio-common/vfprintf-internal.c has the implementation, and it contains
this:

#ifndef COMPILE_WPRINTF
# define vfprintf       __vfprintf_internal

So its vfprintf function is actually __vfprintf_internal.

> BTW, is this the actual function called internally by printf ?

Yes, calls eventually end up there.

Thanks,
Florian
