A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program.
Dereferencing any of these variables could cause a segmentation fault: dereferencing the null pointer generally will cause a segfault, while reading from the wild pointer may instead result in random data but no segfault, and reading from the dangling pointer may result in valid data for a while, and then random data as it is overwritten.
(September 2013) (Learn how and when to remove this message) The interrupt descriptor table ( IDT ) is a data structure used by the x86 architecture to implement an interrupt vector table . The IDT is used by the processor to determine the memory addresses of the handlers to be executed on interrupts and exceptions .
Classes are defined for many of the handle-managed Windows objects and also for predefined windows and common controls. At the time of its introduction, MFC provided C++ macros for Windows message-handling (via Message Maps [9]), exceptions, run-time type identification (RTTI), serialization and dynamic class
Canaries or canary words or stack cookies are known values that are placed between a buffer and control data on the stack to monitor buffer overflows. When the buffer overflows, the first data to be corrupted will usually be the canary, and a failed verification of the canary data will therefore alert of an overflow, which can then be handled, for example, by invalidating the corrupted data.
At that time, C++ was just beginning to replace C for development of commercial software, driven by the rising of the Windows platform and the rapid adoption of object-oriented design. During this period, OWL was a popular choice for Windows application development. In 1992, Microsoft introduced MFC as part of Microsoft C++ 7.0. As a similar ...
An ordering problem that is easy to envision occurs when the data word is transferred byte-by-byte between a big-endian system and a little-endian system and the Fletcher-32 checksum is computed. If blocks are extracted from the data word in memory by a simple read of a 16-bit unsigned integer, then the values of the blocks will be different in ...
In Java, any method can call System.exit(int status), unless a security manager does not permit it.This will terminate the currently running Java Virtual Machine. "The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination."
