# 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] ( [, ] ...) "" # # Example: g_malloc(size_t size) "size %zu" # # The "disable" keyword will build without the trace event. # # The 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 should be a sprintf()-compatible format string. # thread-pool.c thread_pool_submit(void *pool, void *req, void *opaque) "pool %p req %p opaque %p" thread_pool_complete(void *pool, void *req, void *opaque, int ret) "pool %p req %p opaque %p ret %d" thread_pool_cancel(void *req, void *opaque) "req %p opaque %p" #
