Tim-Philipp Müller	3c1d9c6d41	printf: fix alloca use for windows with mingw32 ... Don't use just GLIB_HAVE_ALLOCA_H to check if alloca is available, that's just for the header. GLib may define alloca for us otherwise too irrespective of GLIB_HAVE_ALLOCA_H. Fixes compiler warning with mingw32: gst/printf/vasnprintf.c:73:0: warning: "alloca" redefined	2013-04-12 23:05:58 +01:00
Tim-Philipp Müller	fe7f7135e0	printf: add infrastructure for pointer extensions hook ... Does not do anything yet. On a sidenote, we can't just use %p\001 or so to signal the extension because g-i complains about an invalid ascii character then, so have to resort to something more elaborate, such as %p\aA etc. https://bugzilla.gnome.org/show_bug.cgi?id=613081	2013-04-12 23:05:57 +01:00
Tim-Philipp Müller	8fc876f09f	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	2013-04-12 23:05:56 +01:00
