/* log-for-trace.h: logging basics required by the trace.h generated
* by the log trace backend.
*
* This should not be included directly by any .c file: if you
* need to use the logging functions include "qemu/log.h".
*
* The purpose of splitting these parts out into their own header
* is to catch the easy mistake where a .c file includes trace.h
* but forgets to include qemu/log.h. Without this split, that
* would result in the .c file compiling fine when the default
* trace backend is in use but failing to compile with any other
* backend.
*
* This code is licensed under the GNU General Public License,
* version 2 or (at your option) any later version.
