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.

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.

Thus, the following code will -// cause problems: -// char* str = strdup("impprtantName"); -// TRACE_EVENT_INSTANT0("SUBSYSTEM", str); // BAD! -// free(str); // Trace system now has dangling pointer -// -// To avoid this issue with the |name| and |arg_name| parameters, use the -// TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime overhead. -// Notes: The category must always be in a long-lived char* (i.e. static const). -// The |arg_values|, when used, are always deep copied with the _COPY -// macros. -// -// When are string argument values copied: -// const char* arg_values are only referenced by default: -// TRACE_EVENT1("category", "name", -// "arg1", "literal string is only referenced"); -// Use TRACE_STR_COPY to force copying of a const char*: -// TRACE_EVENT1("category", "name", -// "arg1", TRACE_STR_COPY("string will be copied")); -// std::string arg_values are always copied: -// TRACE_EVENT1("category", "name", -// "arg1", std::string("string will be copied")); -// -// -// Thread Safety: -// A thread safe singleton and mutex are used for thread safety.
