Defined at line 175 of file ../../zircon/system/ulib/trace-provider/include/lib/trace-provider/provider.h

Public Methods

void SetGetKnownCategoriesCallback (GetKnownCategoriesCallback callback)Sets a callback that will be used by `TraceProvider` to collect a list of known categories from
the code that created the provider in order to return them from the fidl `GetKnownCategories`
method. If this value is never set, then the provider defaults to having `GetKnownCategories`
return the list of all categories registered at compile time in the current process. This
callback is an affordance for instances where the categories logged by the provider might not
be captured in the compile-time list. These include meta-providers such as `perfetto-bridge`
and providers from languages other than C++.

bool CreateSynchronously (zx::channel to_service, async_dispatcher_t * dispatcher, const char * name, std::unique_ptr<TraceProvider> * out_provider, bool * out_already_started)Create a trace provider synchronously, and return an indicator of
whether tracing has started already in |*out_already_started|.
Returns a boolean indicating success.
This is done with a factory function because it's more complex than
the basic constructor.
