Abstract
A service and event synchronous/asynchronous manager (SESAM) which provides a programmer interface to concurrency, dispatching and synchronization in an object oriented computing system. SESAM employs a high level framework which is operating system independent, uses threads for asynchrony and independence from operating systems which do not provide for asynchrony, supports a high level "wait-for-event" interface, provides portability of applications and provides synchronization of asynchronous functionality so as to support active object patterns as well as passive object patterns within a single homogenous solution. SESAM includes: (a) at least one dynamic slot providing asynchronous execution of user submitted function; (b) at least one asynchronous timer slot; (c) at least one asynchronous timer slot; (d) at least one exception slot for handling user defined system exception callbacks; (e) at least one slot providing external event notification for user events; (f) a SESAM dispatcher; (g) a pointer to a main operating system dispatcher; (h) a SESAM signaling dispatcher; (i) message block memory for storage of message blocks; (j) a list of SynchHandles that return an error exter…
