| # 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. |
