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#
1e2cf2bc 15# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
94a420b1 16#
a74cd8cc 17# Example: g_malloc(size_t size) "size %zu"
94a420b1 18#
1e2cf2bc 19# The "disable" keyword will build without the trace event.

21# 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.
