Social pressure is a major influence on the scope of exceptions and use of exception-handling mechanisms, i.e. "examples of use, typically found in core libraries, and code examples in technical books, magazine articles, and online discussion forums, and in an organization’s code standards". [10]
They are triggered by software using the INT instruction (either by applications, device drivers or even other interrupt handlers). For example, IBM PC BIOS provides video services at the vector 0x10, MS-DOS provides the DOS API at the vector 0x21, and Linux provides the syscall interface at the vector 0x80.
The condition system is generalized thus: within the handler of a non-serious condition (a.k.a. continuable exception), it is possible to jump to predefined restart points (a.k.a. restarts) that lie between the signaling expression and the condition handler. Restarts are functions closed over some lexical environment, allowing the programmer to ...
Interrupt handlers have a multitude of functions, which vary based on what triggered the interrupt and the speed at which the interrupt handler completes its task. For example, pressing a key on a computer keyboard, [1] or moving the mouse, triggers interrupts that call interrupt handlers which read the key, or the mouse's position, and copy ...
A simple example of this technique could be changing a = a + 1 to a = a – 1. Code mutation produces faults which are very similar to those unintentionally added by programmers. A refinement of code mutation is Code Insertion Fault Injection which adds code, rather than modifying existing code. This is usually done through the use of ...
Each entry of the interrupt vector table, called an interrupt vector, is the address of an interrupt handler (also known as ISR). While the concept is common across processor architectures, IVTs may be implemented in architecture-specific fashions. For example, a dispatch table is one method of implementing an interrupt vector table.
The data that is sent as part of the memory write transaction is used by the chipset to determine which interrupt to trigger on which processor; that data is not available for the device to communicate additional information to the interrupt handler. [1] [2] [3] As an example, PCI Express does not have separate interrupt pins at all; instead ...
Note that the examples given there do not work as-is on modern Windows systems (post XP SP2) due to the changes Microsoft made to address the security issues present in the early SEH design. The examples still work on later versions of Windows if compiled with /link /safeseh:no. "win32: Safe Structured Exception Handling". Yasm manual.
