printf: add our own printf implementation for debug logging We will add support for our own printf modifiers, so we can get nice debug log output on all operating systems irrespective of the specific libc version used. https://bugzilla.gnome.org/show_bug.cgi?id=613081 2013-03-30 15:13:32 +00:00			`/* GLIB - Library of useful routines for C programming`

printf: use sprintf() to work around glibc complaining about %n in a writable format string Don't use snprintf(), but use sprintf instead and do our own length calculations, because glibc may complain about us passing %n in a format string if the string is in writable memory, and here the format string is always in writable memory since we construct it on the fly. This happens if glibc has been compiled with _FORTIFY_SOURCE=2, which seems to be the case on some distros/systems). On the upside, we now use the sprintf code path on all systems which should be better from a maintenance point of view. https://bugzilla.gnome.org/show_bug.cgi?id=697970 2013-04-14 10:23:10 +00:00			`/* Don't use snprintf(); we have to use sprintf instead and do our own`
