[mirror_qemu.git] / include / qemu / log-for-trace.h

/* 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.
