CORE(5) CORE(5) NAME core - format of memory image file DESCRIPTION A memory image of a terminated process is written into file when any of various errors occur; see signal(2). The memory image is written in the process's working directory, if it can be; normal access controls apply. A core file consists of a copy of the user block for the terminated process, followed by an image of its data and stack segments. The user block, which occupies 5K bytes, contains descriptive information about the process and a stack used by the operating system when serving the process; see the include file <sys/user.h>.
