Patent

CA 2629694

A centralized polling system is set forth for providing constant time select call functionality to a plurality of polling tasks in an operating system kernel. In one aspect, the CPS registers for and thereby captures events of interest on a continual basis. Polling tasks are supplied with active events thereby eliminating the need to repetitively poll large numbers of inactive sockets. An exemplary embodiment of the CPS includes a system interface to the operating system kernel, a data structure for maintaining a profile for each of the polling tasks, and an application programming interface for registering the polling tasks, receiving the active sockets and corresponding read/write event types via the system interface, updating the profile within the data structure for each of the polling tasks, and returning the current read and write ready sockets to respective ones of the polling tasks.
