tools lib api: Add debug output support Adding support for warning/info/debug output within libapi code. Adding following macros: pr_warning(fmt, ...) pr_info(fmt, ...) pr_debug(fmt, ...) Also adding libapi_set_print function to set above functions. This will be used in perf to set standard debug handlers for libapi. Adding 2 header files: debug.h - to be used outside libapi, contains libapi_set_print interface debug-internal.h - to be used within libapi, contains pr_warning/pr_info/pr_debug definitions Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1455465826-8426-2-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> 2016-02-14 17:03:42 +01:00			`#ifndef __API_DEBUG_H__`
