Latest Patents
One of Prestifilippo's notable patents is for a "Virtual file system and method." This invention introduces a file accessing scheme that allows logical files to be processed outside of the native operating system and its logical I/O subsystem. When an application program needs to process a file externally, a file information block is created with a special type of file designated as 'virtual.' A pointer within this block directs to a handler, which is a library external to the native operating system. This library processes the file independently, and once completed, the results are returned to the file information block, transferring control back to the application program.
Another significant patent is for "Computer-based methods for determining the head of a linked list." This method involves identifying the head of a linked list stored in memory through a series of steps, including retrieving elements, marking subsequent stored elements, and traversing the list. The process ensures that the stored element not marked is identified as the head of the linked list, enhancing efficiency in data structure management.
