# Trace events for debugging and performance instrumentation## This file is processed by the tracetool script during the build.## To add a new trace event:## 1. Choose a name for the trace event. Declare its arguments and format# string.## 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() -># trace_multiwrite_cb(). The source file must #include "trace.h".## Format of a trace event:## <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"## Example: qemu_malloc(size_t size) "size %zu"## The <name> must be a valid as a C function name.## Types should be standard C types. Use void * for pointers because the trace# system may not have the necessary headers included.## The <format-string> should be a sprintf()-compatible format string.
