MANAGING PROCESS STATE INFORMATION IN AN OPERATING SYSTEM ENVIRONMENT

摘要

A technique for managing process state information involves pushing process state information from the kernel space to the user space in the event of an application crash and generating a core file at the user level instead of at the kernel level, Handling the process state information at the user level instead of at the kernel level provides more flexibility in the generation and management of a core file as compared to systems that use kernel code to generate and manage the core file.A core dump application can be programmed to compress the process state information and/or to extract only certain information from the process state infromation while generating th core file [figure I].
