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
