Re: [ptp-dev] A couple PTP questions
|
Dave,
The createControl() being called three times is on my end.
It may be unavoidable, but I'll look into it.
About canSave vs. isValid, I just wanted you to be aware.
It is not very clear in the articles and documentation about
how they would differ in their implementations.
Regards,
Randy
