Yes, use the "platform process attach" command, or better yet add new API to SBPlatform:

    SBProcess
    SBPlatform::Launch (SBLaunchInfo &launch_info, SBError& error);

    SBProcess
    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.
