Member Function Documentation

◆ AddThread()

NativeThreadLinux & NativeProcessLinux::AddThread	(	lldb::tid_t	thread_id,
		bool	resume
	)

private

Create a new thread.

If process tracing is enabled and the thread can't be traced, then the thread is left stopped with a eStopReasonProcessorTrace status, and then the process is stopped.

Parameters

[in] resume If a tracing error didn't happen, then resume the thread after creation if true, or leave it stopped with SIGSTOP if false.
