From 10827984c2cf54188a9af71b94a7e83197812bb5 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Mon, 23 Oct 2017 13:30:44 +0200 Subject: score: Add _IO_Printf() and _IO_Vprintf() The previous vprintk() implementation had a questionable licence header, lacks support for the 'z' and 'j' format specifiers, is not robust against invalid format specifiers, uses a global variable for output. Replace it with a stripped down version of the FreeBSD kernel kvprintf() function. The new implementation allows a low overhead rtems_snprintf() if necessary. Update #3199. Close #3216. --- cpukit/score/include/rtems/score/io.h | 46 +++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 cpukit/score/include/rtems/score/io.h (limited to 'cpukit/score/include/rtems/score/io.h') diff --git a/cpukit/score/include/rtems/score/io.h b/cpukit/score/include/rtems/score/io.h new file mode 100644 index 0000000000..ae3c57f031 --- /dev/null +++ b/cpukit/score/include/rtems/score/io.h @@ -0,0 +1,46 @@ +/* + * Copyright (c) 2017 embedded brains GmbH.
