Yes, use the "platform process attach" command, or better yet add new API to SBPlatform:
SBPlatform::Launch (SBLaunchInfo &launch_info, SBError& error);
SBPlatform::Attach (SBAttachInfo &attach_info, SBError& error);
Then we can use this API to do the launching/attaching via the SBPlatform object we already have stored.
