1 When a business chooses to hire a temp agency as a permanent employee, the business must pay the temp agency a permanent staffing fee ranging from 10-25% of the employee's first-year salary. Some large organizations have in-house temporary agencies which apply similar fees for their services. 2  For example, the University of Washington charges a 29% markup, with department's paying $18.06 per hour for a temporary employee who actually earns $14 per hour.
Interrupt chaning is a technique used to restore and call all of the interrupt handlers that share that same interrupt number. This is done by saving the previus Interrupt Routine (IR) in a function pointer. Then, installing the new handler, and calling the previus interrupt handler whenever the new IR is called.
(February 2015) In computer systems programming, an interrupt handler, also known as an interrupt service routine or ISR, is a callback function in microcontroller firmware, an operating system, or a device driver whose execution is triggered by the reception of an interrupt.
