3# This file is processed by the tracetool script during the build.
4#
5# To add a new trace event:
6#
7# 1. Choose a name for the trace event. Declare its arguments and format
8# string.
9#
10# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() ->
11# trace_multiwrite_cb(). The source file must #include "trace.h".
12#
13# Format of a trace event:
14#
Stefan Hajnoczi1e2cf2b2010-05-24 11:32:09 +010015# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
Stefan Hajnoczi94a420b2010-05-22 17:52:39 +010016#
Frediano Ziglioa74cd8c2011-08-31 09:25:35 +020017# Example: g_malloc(size_t size) "size %zu"
Stefan Hajnoczi94a420b2010-05-22 17:52:39 +010018#
Stefan Hajnoczi1e2cf2b2010-05-24 11:32:09 +010019# The "disable" keyword will build without the trace event.
Stefan Hajnoczi1e2cf2b2010-05-24 11:32:09 +010020#
Stefan Hajnoczi94a420b2010-05-22 17:52:39 +010021# The <name> must be a valid as a C function name.
22#
23# Types should be standard C types. Use void * for pointers because the trace
24# system may not have the necessary headers included.
25#
26# The <format-string> should be a sprintf()-compatible format string.
