   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.
