1# Trace events for debugging and performance instrumentation
2#
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#
15# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
16#
17# Example: g_malloc(size_t size) "size %zu"
18#
19# The "disable" keyword will build without the trace event.
20#
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.
