#include <interrupts.h>

Public Attributes
uint16_t	address_low_bits
	The low bits of the handler function address.
uint16_t	segment_selector
	The code segment selector in the GDT to use when this interrupt fires.
uint8_t	ist
	The offset into the Interrupt Stack Table (0 if not used) (see TSS)
uint8_t	flags
	Flags: The type of gate this entry represents (0xE for interrupt gate, 0xF for trap gate), The privilege level required to invoke this interrupt and whether the interrupt is present (.
uint16_t	address_mid_bits
	The middle bits of the handler function address.
uint32_t	address_high_bits
	The high bits of the handler function address.
uint32_t	reserved
