 # 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:
 #
 # [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
 #
 # Example: g_malloc(size_t size) "size %zu"
 #
 # The "disable" keyword will build without the trace event.
 #
 # 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.
