3 # This file is processed by the tracetool script during the build.
5 # To add a new trace event:
7 # 1. Choose a name for the trace event. Declare its arguments and format
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".
13 # Format of a trace event:
15 # [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
17 # Example: g_malloc(size_t size) "size %zu"
19 # The "disable" keyword will build without the trace event.
21 # The <name> must be a valid as a C function name.
23 # Types should be standard C types. Use void * for pointers because the trace
24 # system may not have the necessary headers included.
26 # The <format-string> should be a sprintf()-compatible format string.
