See also: unique ID  

entry observer

A class implemented by a messaging client that is notified when the data representing an individual entry changes, or when requested access to a message store has been successfully gained.

entry point

A function which is called when the DLL is loaded, or attached by a thread or process. In Symbian OS, the function E32Dll() is usually coded as the entry point.

See also: DLL  export  

entry symbol
