摘要
A method and system for allowing multiple tasks to share virtual memory areas, in a memory management system for a computer, uses a data structure which maintains a list of address spaces shared by more than one task. For each entry in this list, a list of slots in virtual address space is maintained in the data structure, where each slot contains indications that said shared memory was mapped into a task. An offset table of directory pages is also maintained, and each entry in this directory points to a directory page for a task. The directory page entries for all of such directory pages points to a page table entry. An entry in each of the offset tables points to the entry in the list of shared address spaces for this set.
