Whereas RTC_LOG's +-// categories are statically defined, TRACE categories are created +-// implicitly with a string. For example: +-// TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent") +-// +-// Events can be INSTANT, or can be pairs of BEGIN and END in the same scope: +-// TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly") +-// doSomethingCostly() +-// TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly") +-// Note: our tools can't always determine the correct BEGIN/END pairs unless +-// these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you +-// need them to be in separate scopes. +-// +-// A common use case is to trace entire function scopes. This +-// issues a trace BEGIN and END automatically: +-// void doSomethingCostly() { +-// TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly"); +-// ... +-// } +-// +-// Additional parameters can be associated with an event: +-// void doSomethingCostly2(int howMuch) { +-// TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly", +-// "howMuch", howMuch); +-// ... +-// } +-// +-// The trace system will automatically add to this information the +-// current process id, thread id, and a timestamp in microseconds. +-// +-// To trace an asynchronous procedure such as an IPC send/receive, use +-// ASYNC_BEGIN and ASYNC_END: +-// [single threaded sender code] +-// static int send_count = 0; +-// ++send_count; +-// TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count); +-// Send(new MyMessage(send_count)); +-// [receive code] +-// void OnMyMessage(send_count) { +-// TRACE_EVENT_ASYNC_END0("ipc", "message", send_count); +-// } +-// The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs. +-// ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process. +-// Pointers can be used for the ID parameter, and they will be mangled +-// internally so that the same pointer on two different processes will not +-// match. For example: +-// class MyTracedClass { +-// public: +-// MyTracedClass() { +-// TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this); +-// } +-// ~MyTracedClass() { +-// TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this); +-// } +-// } +-// +-// Trace event also supports counters, which is a way to track a quantity +-// as it varies over time. Counters are created with the following macro: +-// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue); +-// +-// Counters are process-specific. The macro itself can be issued from any +-// thread, however. +-// +-// Sometimes, you want to track two counters at once. You can do this with two +-// counter macros: +-// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]); +-// TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]); +-// Or you can do it with a combined macro: +-// TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter", +-// "bytesPinned", g_myCounterValue[0], +-// "bytesAllocated", g_myCounterValue[1]); +-// This indicates to the tracing UI that these counters should be displayed +-// in a single graph, as a summed area chart. +-// +-// Since counters are in a global namespace, you may want to disembiguate with a +-// unique ID, by using the TRACE_COUNTER_ID* variations. +-// +-// By default, trace collection is compiled in, but turned off at runtime. +-// Collecting trace data is the responsibility of the embedding +-// application. In Chrome's case, navigating to about:tracing will turn on +-// tracing and display data collected across all active processes. +-// +-// +-// Memory scoping note: +-// Tracing copies the pointers, not the string content, of the strings passed +-// in for category, name, and arg_names.
