## Detailed Description

PVCommandStatusObserver Class

PVCommandStatusObserver is the PV SDK observer class for notifying the status of issued command messages. The API provides a mechanism for the status of each command to be passed back along with context specific information where applicable. Applications using the PV SDKs must have a class derived from PVCommandStatusObserver and implement the pure virtual function in order to receive event notifications from a PV SDK. Additional information is optionally provided via derived classes.
