| 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. |
