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