A hardware interrupt is a condition related to the state of the hardware that may be signaled by an external hardware device, e.g., an interrupt request (IRQ) line on a PC, or detected by devices embedded in processor logic (e.g., the CPU timer in IBM System/370), to communicate that the device needs attention from the operating system (OS) [7] or, if there is no OS, from the bare metal ...
In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).
In some cases, a "Resume" button would be available, allowing the user to dismiss the dialog and force the offending program to quit, but most often the resume button would be disabled and the computer would have to be restarted. Originally, the resume button was unavailable unless the running program had provided the OS with code to allow ...
C Traps and Pitfalls is a slim computer programming book by former AT&T Corporation researcher and programmer Andrew Koenig, its first edition still in print in 2017, which outlines the many ways in which beginners and even sometimes quite experienced C programmers can write poor, malfunctioning and dangerous source code.
Because spurious wakeup can happen, when a thread wakes after waiting on a condition variable, it should always check that the condition it sought is still satisfied. If it is not, it should go back to sleeping on the condition variable, waiting for another opportunity. [5]
A single trampoline suffices to express all control transfers of a program; a program so expressed is trampolined, or in trampolined style; converting a program to trampolined style is trampolining. Programmers can use trampolined functions to implement tail-recursive function calls in stack-oriented programming languages. [1]
