Subject: Difference between caput/caget and PVwrite

Dear EPCIS-community,

I´m experimenting with some issues while using a driver based on the AsynPortdriver (C++) and I would like to know more information about what are the main differences while executing caput and using CSS-BOY for setting a variable value.

My problem is that in my application, everything goes well if I set a value using CSS-BOY, but the system runs into a segmentation fault if I use two consecutive times the same variable using caput. It seems that at some point it is freeing some variable that has already been freed, but it is ok if CSS-BOY carried out the set.

Which step is CSS-BOY carrying out that caput does not include?
Any advice is appreciated.
Best regards
Pilar
