A static library for publishing a trace provider. The trace manager connects to trace providers to collect trace records from running programs.
To register the trace provider, the program must call
trace_provider_create() at some point during its startup sequence. The trace provider will take care of starting and stopping the trace engine in response to requests from the trace manager.
This library exists for very special cases, and in general should not be used.
To use it, you will need to provide your own connection with trace-manager. This library does not come with the fdio support that the “normal” version of this library uses. See fdio_connect.cpp in this directory for boilerplate of what needs to be done. Then when you have the handle to trace-manager, call trace_provider_create_with_name().
trace_provider_t* trace_provider_create_with_name( zx_handle_t to_service_h, async_dispatcher_t* dispatcher, const char* name);
You will need to add these dependencies to your BUILD.gn file:
