1 # Trace events for debugging and performance instrumentation 2 # 3 # This file is processed by the tracetool script during the build. 4 # 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. 27 28 # thread-pool.c 29 thread_pool_submit(void *pool, void *req, void *opaque) "pool %p req %p opaque %p" 30 thread_pool_complete(void *pool, void *req, void *opaque, int ret) "pool %p req %p opaque %p ret %d" 31 thread_pool_cancel(void *req, void *opaque) "req %p opaque %p" 32 33 #
